Add support for ppc64le (PowerPC 64bit little endian)
Submitted by Michel Normand
Link to original bug (#745433)
Description
with orc 0.4.22 the make check is failing
FAIL: test-limits
investigation identified two related required changes:
- m4/as-host-defines.m4
to define HAVE_POWERPC for ppc64le. - orc/orcprogram-altivec.c
to add support of ppc64le (that is PowerPC ABI V2)
at least epilog/prolog differs, but need to check all file.
