[oe] [meta-oe][PATCH 0/3] libhugetlbfs: fix build problems with ix86 and armv7ab

[Gary S. Robertson]

OE builds of libhugetlbfs were failing for armv7ab and i586 (qemux86)
architectures.  In addition, once patched so builds completed, execution of
some tests was failing for armv7ab.

Patched OE recipe and Makefile to add support for 32-bit ix86 architectures...
(patches 1 and 2).
Then patched linker control script to include armv7ab in the set of
architectures whose text section offset and page size were corrected by
the script...(patch 3).

Patches 2 and 3 have been submitted upstream to the libhugetlbfs maintainers
and acceptance has been indicated for both...
however patch 2 has yet to appear in the upstream repository,
while patch 3 has been verified as merged.

OE builds of libhugetlbfs with these patches added have been successfully
completed here for qemux86, qemux86_64, armv7a, armv7ab, armv8, and armv8b
platforms, and tests run successfully on all except armv8b - which failed
with unrelated boot time issues.
