Log Message:
-----------
Don't use -m96bit-long-double gcc option in configure builds.

This option is seemingly not necessary (any more?) and it results in internal
compiler errors when building using g++ 4.9.1, see

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63402

Simply remove it as it's not used in the makefile builds neither.
