Fwd: patch proposal for acinclude.m4 to better support gcc on illumos/smartos

As this seemed to fall upon deaf ears, I'll reiterate my request for
integration of the following patch which fixes the fact that the linker
directive '-as-needed' is not supported by Solaris ld.

As /usr/bin/ld on illumos doesn't (yet) support --as-needed, this patch
to acinclude.m4 will suppress the LDFLAGS -Wl,-as-needed passed when gcc
is used as the compiler in the "bash bootstrap" command.

This patch assumes that all gcc variants running on illumos (gcc3 and
gcc4) are configured with --without-gnu-ld --with-ld=/usr/bin/ld,
which after brief research, seems typically the case.

This has been tested and seems to work fine on oi_151a7 with gcc47 under
pkgsrc http://pkgsrc.smartos.org/packages/illumos/2012Q3/All
