Laurent Vivier 33143c446e linux-user: fix ELF load alignment error 
When we try to use some targets on ppc64, it can happen the target
doesn't support the host page size to align ELF load sections and
fails with:

  ELF load command alignment not page-aligned

Since commit a70daba377 ("linux-user: Tell guest about big host
page sizes") the host page size is used to align ELF sections, but
this doesn't work if the alignment required by the load section is
smaller than the host one.  For these cases, we continue to use the
TARGET_PAGE_SIZE instead of the host one.

I have tested this change on ppc64, and it fixes qemu linux-user for:
  s390x, m68k, i386, arm, aarch64, hppa
and I have tested it doesn't break the following targets:
  x86_64, mips64el, sh4
mips and mipsel abort, but I think for another reason.
