You can build tests without running them simply by running "make check" 
for a cross-compiled glibc without test-wrapper set.  (I've done a variant 
of that - "make math/tests" with some -j option to build the math/ tests 
in parallel, then "make regen-ulps" with test-wrapper set to run those 
tests needed for ulps regeneration.)

Many tests depend on aspects of the test environment and aren't designed 
to be installed and run without a glibc source and build tree present.
