patchelf: add patch to fix relative rpath issue on big-endian systems

This commit adds a patch to the host package patchelf to fix an issue
with endianness when the --make-rpath-relative option is
specified. Currently, patchelf does not take into account the
architecture of the target ELF when it performs the fixup on the
RPATH. Thus, if it differs from the host in endianness, the RUNPATH
field will be invalid. The patch fixes the bug reported here:
