Bug Description:
When MACHINE=qemux86 and using uclibc, the compilation of
gcc-cross-intermedia-4.4.2 failed and reported the following error information:
bid_decimal_globals.c:47:18: error: fenv.h: No such file or directory
bid_decimal_globals.c: In function '__dfp_test_except':
bid_decimal_globals.c:59: error: 'FE_INEXACT' undeclared (first use in this
function)

once
bid_decimal_globals.c:59: error: for each function it appears in.)

Bug always appeared.

How to reproduce:
1. Check out openembedded and swich to org.openembedded.dev branch;
2. Set  MACHINE = qemux86 DISTRO=micro-uclibc or 
MACHINE = qemux86 DISTRO=minimal-uclibc into your local local.conf
3. bitbake base-image.
4. The error will appear.

QA TODO:
1. Validate other version of gcc to check whether or not the same error exists.
2. Validate other distribution which using uclibc to check whether or not  the
same error exists.
3. I have validated the arm platform and mips platform have not the same error,
but have not validated other platforms, e.g: PPC, blackfin.
