[PATCH] Add VxWorks fixincludes hack, kernel math.h FP_ constants

[Olivier Hainque via Gcc-patches]

Hello,

The attached patch adds a fixincludes add for VxWorks
to add missing FP_ constant definition to math.h, intended
for old versions of the kernel math.h header.

As the other patches in the series, this helps libstdc++
build failures for old versions of VxWorks, 6.9 in particular
for which we were able to get a successful complete build
after this.

Also bootstrapped and regression tested ok for x86_64-linux,
just in case.

Ok to commit?

Thanks in advance,

With Kind Regards,

Olivier
