Hi!
If say /usr/bin/gcc-ar doesn't find /usr/<target>/bin/ar (and a few others),
it gives up unless CROSS_DIRECTORY_STRUCTURE, while e.g. collect2 looks for
ld, nm etc. in $PATH. The collect2.c snippet is:
/* Search the compiler directories for `ld'. We have protection against
recursive calls in find_a_file. */
if (ld_file_name == 0)
ld_file_name = find_a_file (&cpath, ld_suffixes[selected_linker]);
/* Search the ordinary system bin directories
for `ld' (if native linking) or `TARGET-ld' (if cross). */
if (ld_file_name == 0)
ld_file_name = find_a_file (&path, full_ld_suffixes[selected_linker]);
where the difference between full_ld_suffixes and ld_suffixes is
exactly a concat (target_machine, "-", ld_suffixes[xxx], NULL);
Here is so far untested attempt to do that in gcc-{ar,nm,ranlib} too, ok if
bootstrap/regtest passes and testing shows it works (for 4.8 too, in 4.7 it
worked)?
