libhugetlbfs: x86 - don't link against host libs

An earlier patch from Chunrong Guo <B40290@freescale.com> fixed the
linker command scripts in ldscripts to comment out hard-coded paths
for the linker search directories.  This allows the command line
to specifiy the proper paths without being overridden.
However, the 32-bit ix86 scripts evidently were added after this
earlier patch was created and were not corrected by it - so here
we simply duplicate the technique in the earlier patch and extend it
to correct the linker scripts for 32-bit ix86 builds.

+Subject: [PATCH] libhugetlbfs: x86 avoid host library search in cross-dev
+
+Upstream-Status: Inappropriate [oe-core specific]
+
+The ldscripts for 32-bit ix86 architectures were not corrected by the earlier
+patch from Chunrong Guo <B40290@freescale.com>... presumably they were added
+after that patch was created.  Here we extend the same technique to include
+the 32-bit ix86 linker scripts, so the command line variables can set the
+linker search directories rather than using hard-coded paths in the ldscripts.
