Subject: [PATCH 2/3] elf/ld.so: keep compatible with the original policy of
the LD_HUGEPAGE_LIB env
When we use new policy: ld.so load PT_LOAD segement use hugepage according to
PF_HUGEPAGE flag. We should keep compatible with the original policy of
the LD_HUGEPAGE_LIB env which loads all the PT_LOAD segment try to use
hugepage.
