Unfortunately, libtool has no way of telling if unrecognized

compiler flags need an argument or not, and can disect options and
pass parts through incorrectly.  This changeset reverts both

* config/ltmain.in (func_mode_link): Pass through options needed
to compile in 64-bit mode with gcc, and the SGI, Sun, HP and IBM
compilers.
