libc/uClibc: add option to enable fenv

Support for fenv.h is a little bit more tricky that enabling it only
for x86-32 is not right.

Add an option for the user to choose whther to install fenv.h or not.

        There are two versions of linuxthreads.  The older (stable) version

    16
        has been in uClibc for quite a long time but hasn't seen too many

        updates other than bugfixes.

        The new version has not been tested much, and lacks ports for arches
yann@1977
    25
        which glibc does not support (like bfin/frv/etc...), but is based on
yann@1977
    26
        the latest code from glibc, so it may be the only choice for the
yann@1977
    27
        newer ports (like alpha/amd64/64bit arches and hppa).

      you can try switching this off.

      fenv.h provides functions to control the floating point environment,

yann@3276
    76
yann@3276
    77
      For some architectures, fenv.h is incomplete, so is not installed
yann@3276
    78
      by default. x86 is known to have a rather complete fenv.h, so it is
yann@3276
    79
      installed by default only for x86.
yann@3276
    80
yann@3276
    81
      If you need fenv.h on other architectures, say 'y' here, but you may
yann@3276
    82
      encounter some issues.
