The test case is for targets that support FMA. Previously
the "target" selector is missed in dg-final command.

Tested on x86_64-pc-linux-gnu.

Thanks

gcc/testsuite/ChangeLog:

        * gcc.dg/pr110279-1.c: add target selector.

Rather than list targets explicitly in the test, wouldn't it be better 
to have a common routine that could be used in other cases where we have 
a test that requires FMA?

So something similar to check_effective_target_scalar_all_fma?

Here is an updated version of the patch. Sorry I'm not very familiar
with the testsuite commands.

gcc/testsuite/ChangeLog:

        * gcc.dg/pr110279-1.c: add target selector.
