[Bug fortran/34128] slow gfortran 4.x (library?) compared to g77 3.4

It's 64-bit only, and it appears to be a glibc bug: with glibc on x86_64,
sinf((float) integer_variable) is slower than (float)sin((double)
integer_variable). Paul Brook looked into it a bit, and said that while glibc's
sin() was clearly well optimized, its sinf() was poor.
