python-numpy: uClibc patch to avoid ldexpl and frexpl

It turns out that uClibc only enables the long double math functions
for some architectures (god know why, so what if long double is the
same as double, these functions should still be defined). Since
python-numpy links with those functions, the module will fail to load
on ARM, MIPS and SH.

However, python-numpy actually checks for each function if it is really
available. Only, it overrides that check for ldexpl and frexpl when
long double is the same as double (i.e. in exactly the case the uClibc
doesn't have these functions).

So add another exception for this.
