[PATCH] Fix 30808 gprofng tests failed

[vladimir.mezentsev@oracle.com]

From: Vladimir Mezentsev <vladimir.mezentsev@oracle.com>

In gprofng testing, we need a tempory gprofng installation to resolve run-time
dependencies on libraries (libgprofng, libopcodes, libbfd, etc).
We set LD_LIBRARY_PATH and GPROFNG_SYSCONFDIR to find our libraries and
configuration file. These variables must be set for all gprofng tests.

Tested on aarch64 and x86_64 with and without --enable-shared and --target=<>.

	* testsuite/config/default.exp: Make a temporary install dir.
	Set LD_LIBRARY_PATH, GPROFNG_SYSCONFDIR.
	* testsuite/lib/Makefile.skel: Move LD_LIBRARY_PATH and
	GPROFNG_SYSCONFDIR setting in testsuite/config/default.exp.
