Hi Dave, ld-elf/pr20995-2 is what brought this to my attention. Also, any of
the following.

As far as a fix for this goes, if you're sure that pr12376 isn't really just a
kernel issue (see https://sourceware.org/bugzilla/show_bug.cgi?id=12376#c8)
then hppa can still support relro by page aligning data then following that
with DATA_SEGMENT_ALIGN (${MAXPAGESIZE}, ${COMMONPAGESIZE}). This will waste
up to 2*MAXPAGESIZE-2 bytes of memory before the start of the relro area, the
first page for the hardware/kernel issue, the second to align the end of the
relro area to a page.
