[Bug math/1384] New: test-float and test-double failures compiling with gcc-4.1

["sjmunroe at us dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

It seems that gcc-4.1 is getting getting more agressive using the powerpc
fused-multiply-add (fmadd) which impacts the code gen for the bessel functions
in ./dbl-64/e_j1.c, ./dbl-64/e_j1.c, ./flt-32/e_j1f.c, ./flt-32/e_j1f.c. The
changes the rounding a bit and results in a 1-2 bit (ulp) difference in the
result from the code generated by gcc-3.4. This only seemd to impacts the y1()
yn() functions.
