Do not capture the build-time value of $PATH in the 'emacs' executable
since this can noticeably increase the size of the closure of Emacs
with things like GCC being referenced.

gnu: emacs: Do not keep references to the entries of the build-time $PATH. This reduces the number of references of the output from 54 to 31, removing references notably to gcc, expat, glib:bin, ld-wrapper-0, texinfo, pkg-config, make, gawk, binutils, etc. Reported by David Thompson. * gnu/packages/patches/emacs-exec-path.patch: New file. * gnu-system.am (dist_patch_DATA): Add it. * gnu/packages/emacs.scm (emacs)[source]: Use it. 2015-04-13 17:09:06 -04:00			`Do not capture the build-time value of $PATH in the 'emacs' executable`
