A number of i386 math optimisation tests are looking assembly instructions
that are only emitted when the compiler knows the target has a C99 libm
available. Since targets like *-elf may not have such a libm, a C99 runtime
requirement is added to these tests.
Tested on x86-elf and x86_64-elf hosted on x86_64-linux in addition to
x86_64-pc-linux-gnu
If approved, I'll need a maintainer to kindly commit on my behalf.
Thanks,
