- Subject: Fix ACX_LARGEFILE to use canonical host/target names
The ACX_LARGEFILE macro checks the values of $host and $target, which
may or may not be canonical names at this point depending on which
other macros have been called first; it should require
AC_CANONICAL_HOST and AC_CANONICAL_TARGET to ensure they are both
canonical. This shows up as build failures for GDB configured
--build=i686-pc-linux-gnu --host=i686-solaris2.10
--target=i686-solaris2.10. OK to commit this patch (GCC and src),
with regeneration of the GDB and binutils configure scripts that use
ACX_LARGEFILE?

* largefile.m4 (ACX_LARGEFILE): Require AC_CANONICAL_HOST and
AC_CANONICAL_TARGET.
