description:
Soft-float support for rounding mode is currently not thread-safe, which
is not acceptable. Decision should be made on whether full fenv.h
support is desirable and then fix this appropiately.

Math functions (both libc and libm) should not touch errno, this creates
unnecessary problems for compilers.
