- sed/patch the source (gcc/gcc.c) so the hard-codes /usr/lib gets replaced by /tools/lib:
sed -i "/standard_exec_prefix_/s%/usr%/tools%g" gcc/gcc.c
My preference would be the sed/patch, because it removes all the hardcoded host-dirs from gcc's search-path.
For consistency, make it sed -i "/standard_exec_prefix_/s%/usr%/cross-tools%g"
Probably better to just remove it from the addition to the library search path
(only standard_exec_prefixes_2) when cross-compiling...
Two patches attached, choose one or the other...
First removes standard_exec_prefixes_2 from the library search path when
cross-compiling (ie removes /usr/lib/gcc/${TARGET}/${VER} )Second does the above but also removes /usr/libexec/gcc/${TARGET}/${VER}
and /usr/lib/gcc/${TARGET}/${VER} from the gcc executable search path
when cross-compiling
(why gcc should search outside its prefix for its binaries is beyond me
when cross-compiling, not that it would ever get there...)Will add comments to the top in lfs-style patch submission format if one or the other are accepted...
Patches are safe to apply to all gcc builds...

Removes standard_exec_prefix_2 from library search path when cross-compiling
