Subject: [PATCH] Don't blindly enable frexpl and ldexpl for uClibc
When the size of double and long double are equal, numpy blindly
assumes that frexpl and ldexpl will be available as well. But for
uClibc, that's not true: it only defines the long double functions
when long double "exists" on the architecture.
So make an exception for uClibc.
