The glibc.sh script doesn't handle the glibc versions with
an underscore very well (bash expected integer error). I
have attached a small patch for that. Instead of looking
for "not period" I changed the sense to look for numbers.
I initially tried to make it look for either a period or
an underscore, but that didn't work like I wanted (probably
because I did something wrong).

Original patch modified to be more robust.

fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
