[RFA:] ld-elf/sec64k.exp

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

As promised.  The expected readelf output pattern works for
cris-axis-linux-gnu,
i?86-pc-linux-gnu,
x86_64-unknown-linux-gnu,
powerpc-unknown-linux-gnu,
sparc-unknown-linux-gnu,
sparc64-unknown-linux-gnu,
which if nothing else gives (me) a confidence in the 32/64-bit
rel/rela and machine-general properties of the test.

It does not work on mips-unknown-linux-gnu, because that
assembler seems to output *both* a .rel and a .rela section,
where one (I forgot which) is empty.  Accommodating that
wart-or-bug would affect the integrity of the test, IMHO.

Anyway, the test is currently disabled elsewhere than cris-*-*
because of the mentioned performance problems (again, seemingly
somewhere below lang_place_orphans).

Ok to commit?

	* ld-elf/sec64k.exp: New test.
