patch breaks libgloss builds

[Eric Christopher]

Building crt0.S we fail on this instruction:

li t2,0xAAAA5555

with a mipsisa64-elf toolchain.

Interestingly enough the code that I think you added in reporting bad
numbers is failing too:

/dzur/sourceware/combined/libgloss/mips/crt0.S: Assembler messages:
/dzur/sourceware/combined/libgloss/mips/crt0.S:91: Error: Number
(0x0aaaa5555) larger than 32 bits

I'll take a look at it later, just noticed it yesterday.
