partly revert detection of broken float in configure
commit 80fbaac4cd1930e9545a5d36bf46ae49011d2ce8 broke all soft-float
archs, where gcc defines __GCC_IEC_559==0 because rounding modes and
exception flags are not supported. for now, just check for
__FAST_MATH__ as an indication of broken float. this won't detect all
possible misconfigurations but it probably catches the most common
one.
