Fix 31252 gprofng causes testsuite parallel jobs fail

Before running our tests, we made a fake installation into ./tmpdir.
This installation changes libopcodes.la in the build area.
Gas testing may fail if gas and gprofng tests are run in parallel.

I create a script to run gprofng. Inside this script, LD_LIBRARY_PATH,
GPROFNG_SYSCONFDIR are set.
putenv_libcollector_ld_misc() first uses $GPROFNG_PRELOAD_LIBDIRS to create
directories for SP_COLLECTOR_LIBRARY_PATH ($SP_COLLECTOR_LIBRARY_PATH is used
to set up LD_PRELOAD).
