i followed the solution in libgomp for passing
offloading parameters.

it seems TESTING_IN_BUILD_TREE is not set in
target lib site.exp so that should be wired
up somehow.

i'm not sure how installed testing works, if
it does not use the build tree site.exp, then
i can try to add BUILD_CC to site.exp.
(there is an EXTRA_DEJAGNU_SITE_CONFIG hook)
