* Makefile.am (.scm.go): Use `pre-inst-env' instead of re-defining the
environment variables, except for `DISTRO_INSTALLED_PATCH_DIRECTORY'
and `DISTRO_INSTALLED_BOOTSTRAP_DIRECTORY'.
* distro/packages/base.scm (gcc-4.7)[arguments]: In the `pre-configure'
phase, patch all the relevant gcc/config files, not just those for
x86_64-linux-gnu.
* guix/build/utils.scm (substitute*): Remove special syntax for
list-of-files; instead, check whether FILE is `list?' at run time.
* distro/packages/base.scm (gcc-4.7, %binutils-static): Adjust
accordingly.
* guix/packages.scm (package-source-derivation): Add `system'
parameter. Pass it to METHOD.
(package-derivation)[expand-input]: Pass SYSTEM to
`package-derivation' and `package-source-derivation'.
* distro/packages/base.scm (package-with-bootstrap-guile)[boot]: Pass
SYSTEM to FETCH.
* guix/derivations.scm (imported-files): Call
`build-expression->derivation' with SYSTEM, not (%current-system).
(build-expression->derivation): Pass SYSTEM to `imported-modules' and
`compiled-modules'.
* guix/derivations.scm (%guile-for-build): Initialize to #f.
(imported-files, imported-modules, compiled-modules): Add `guile'
keyword parameter. Pass it down to `build-expression->derivation'.
(build-expression->derivation)[guile-drv]: New variable. Pass it as
the #:guile parameter for `imported-modules' and `compiled-modules'.
* tests/derivations.scm: Set %GUILE-FOR-BUILD to the derivation of
%BOOTSTRAP-GUILE.
* distro/packages/base.scm (%glibc-stripped): Copy all of Linux-Libre's
`include/asm' directory; copy a few linux/ headers too.
(%bootstrap-glibc): Update tarball hash.
* distro/packages/base.scm (%static-inputs): Add an `awk' -> `gawk', and
`sh' -> `bash' symlinks. Add `fgrep' and `egrep'.
(%bootstrap-coreutils&co): Use new tarball that contains that
symlink.
* distro/packages/bootstrap/x86_64-linux/bash,
distro/packages/bootstrap/x86_64-linux/mkdir,
distro/packages/bootstrap/x86_64-linux/tar,
distro/packages/bootstrap/x86_64-linux/xz: Use binaries from that
tarball (the previous binaries hadn't gone through
`remove-store-references', which is fixed now.)
* guix/derivations.scm (imported-files)[parent-dirs]: Move to...
(parent-directories): ... here. New procedure.
(compiled-modules): New procedure.
(build-expression->derivation): Use it.
* tests/derivations.scm ("build-expression->derivation with modules"):
New test.
* guix/packages.scm (package-derivation)[intern]: New procedure. Pass
#t as the `recursive?' argument, instead of #f.
[expand-input]: New procedure, with code formerly in the body.
Support inputs where the input is a procedure returning a file name or
an <origin>.
Use `expand-input' in the body.
* tests/packages.scm ("trivial with system-dependent input"): New test.
* distro/packages/base.scm (tarball-package): New procedure.
(%bootstrap-binaries-tarball): New variable.
(%guile-bootstrap-tarball): Define in terms of `tarball-package'.
* guix-build.in (derivations-from-package-expressions): New `system'
parameter. Pass it to `package-derivation'.
(%default-options): Add `system' pair.
(show-help): Describe `--system'.
(%options): Add it.
(guix-build): Check the `system' pair in OPTS; pass it to
`derivations-from-package-expressions' and `package-derivation'.
* guix/build/http.scm (open-connection-for-uri): New procedure.
(http-fetch): Use it. Pass the result as a #:port argument to
`http-get'.
Add hack to modify the `set-port-encoding!' binding in (web response).
* guix/ftp-client.scm (ftp-open): Add optional `port' parameter,
defaulting to 21. When calling `getaddrinfo', convert PORT to a
string and pass AI_NUMERICSERV when PORT is a number.
