All objects using test/util.c fail to link:
| CCLD region-test
| /usr/bin/ld: utils.o: in function enable_fp_exceptions:utils.c(.text+0x939): error: undefined reference to 'feenableexcept'
There's indeed no explicit dependency on -lm, and if HAVE_FEENABLEEXCEPT
happens to be set, test/util.c uses feenableexcept(), which is nowhere
to be found while linking.
Fix this by adding -lm to TEST_LDADD, although two alternatives could be
thought of:
- Only specifying -lm for objects using util.c.
- Introducing a conditional to add -lm only when configure detects
have_feenableexcept=yes.
