| Disable fenv.h support for uClibc-based toolchains. |
| |
| 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. Bug was reported upstream: |
| https://svn.boost.org/trac/boost/ticket/11756 |
