package/boost: Disable fenv support with uClibc

Browse Source 
The boost build system does not recognize the fact that fenv.h is an
optional module in uClibc and tries to use it even if UCLIBC_HAS_FENV
is disabled. This patch disables fenv support completely when compiling
with a uClibc-based toolchain.
