Subject: [PATCH] Add powerpc little-endian (ppc64le) flags
4fe85b
4fe85b
libgcc dependency was removed *just* for this target because
4fe85b
the distros that use ppc64el doesn't have 32-bit support on it.
4fe85b
4fe85b
* configure.ac: Add targets for powerpc64el and skip libgcc.
4fe85b
* Makefile.am: Likewise.
