[PATCH] Apply ld-arm/gc-hidden-1 to all ELF targets, not just *eabi* targets

[Roland McGrath]

The ld-arm/gc-hidden-1.d test has "target: arm*-*-*eabi*" and so it is not
getting tested on ELF ARM targets that don't have eabi in the OS name.
Other ELF-only test cases in that directory have no "target:" line
and instead just a "not-target:" line that excludes a list of targets
intended to cover all the non-ELF cases.

This changes that case to use the same target selection as all the other
similar cases in that directory.

This makes it start being run for arm-nacl targets, which are ELF (and even
EABI-based), but don't have eabi anywhere in the name.  On arm-nacl
targets, the address space layout is different so overly-specific regexps
embedding particular addresses do not match.  Those addresses have nothing
to do with what this case is trying to test, so I generalized the regexps
to be indifferent to the exact addresses.  With these changes, the test
passes for arm-nacl targets.

No regressions in 'make check-ld' on both trunk and 2.24 branch.
OK for trunk and 2.24 branch?


Thanks,
Roland

	* ld-arm/gc-hidden-1.d: Remove target, add not-target to match
	other ELF-only tests in this directory.  Loosen regexps so they
	don't care what the exact addresses are.
