Subject: [PATCH] Add powerpc little-endian (ppc64le) flags
a85e8e
a85e8e
libgcc dependency was removed *just* for this target because
a85e8e
the distros that use ppc64el doesn't have 32-bit support on it.
a85e8e
a85e8e
* configure.ac: Add targets for powerpc64el and skip libgcc.
a85e8e
* Makefile.am: Likewise.
