In ./gcc/libgcc.mvars, we have

  SHLIB_INSTALL = $(mkinstalldirs) $(DESTDIR)$(slibdir)@shlib_slibdir_qual@;
[...]

where $(DESTDIR)$(libdir) seems to be correct for me. However, the last part
(@shlib_slibdir_qual@) is substituted in libgcc/Makefile.in(install-shared)
with $(MULTIOSSUBDIR) which is based on `$(CC) $(CFLAGS)
-print-multi-os-directory)`, here '../lib64'.


Hope this helps and rings a bell with someone ...?!
