Clang attempts to guess file names based on the OS and distro (yes!),
|
|
but unfortunately, that doesn't work for us.
|
|
|
|
This patch makes it easy to insert libc's $libdir so that Clang passes the
|
|
correct absolute file name of crt1.o etc. to 'ld'. It also disables all
|
|
the distro-specific stuff and removes the hard-coded FHS directory names
|
|
to make sure Clang also works on foreign distros.
