[committed] Fix PR testsuite/38864

[Adam Nemet]

As explained in the PR these tests rely on fixed-point support but the
target-check was removed by Richard MIPS's testsuite improvements.  This patch
puts the check back.  The patch was approved in the PR.

Tested with mips.exp on mipsisa64r2-elfoabi configured with and without
fixed-point.
