--- Comment #44 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
All configure --with-* and --enable-* options are stored in shell variables
named with_* and enable_*, respectively, so it's just a matter of testing for
yes (for --enable) or rather for no (for explicit --disable). Look for e.g.
--enable-initfini-array around line 1932 in $top_srcdir/gcc/configure.ac, or
with_avrlibc around line 1495 in gcc/config.gcc; you can do something similar
in gcc/config.host, without any explicit argument passing, because the
config.{host,gcc} files are sourced by configure, so they inherit all shell
variables.
