elf: Do not run IFUNC resolvers for LD_DEBUG=unused [BZ #24214]fw/bug24214
This commit adds missing skip_ifunc checks to aarch64, arm, i386,
sparc, and x86_64. A new test case ensures that IRELATIVE IFUNC
resolvers do not run in various diagnostic modes of the dynamic
loader.
Tested on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
s390-linux-gnu, s390x-linux-gnu, powerpc64le-linux-gnu. Built with
build-many-glibcs.py.
