[OMPI devel] [PATCH] ompi_get_libtool_linker_flags.m4: fix $extra_ldflags detection

[Bert Wesarg]

Hello,

when using a multi token CC variable (like "gcc -m32"), the logic to
extract $extra_ldflags from libtool don't work. So here is a little hack
to remove the $CC prefix from the libtool-link cmd.
