[oe] python-numpy_1.4.1: task `compile` fails with `numpy/core/include/numpy/ufuncobject.h:309:18: fatal error: fenv.h: No such file or directory`

[Paul Menzel]

Dear OE folks,


task `compile` fails with `minimal-uclibc` for `MACHINE = "beagleboard"`
and `binutils_2.21.bb` with the following error.

`fenv.h` is available though.
