[Bug target/35425] New: Improve -mpcXXX handling

[hjl dot tools at gmail dot com]

bash-3.2$ touch x.c  
bash-3.2$ /usr/gcc-4.3/bin/gcc -mpcfooo -S x.c  
x.c:1: error: pc0 is not valid precision setting (32, 64 or 80)
bash-3.2$ /usr/gcc-4.3/bin/gcc -mpc80x -S x.c  
bash-3.2$ 

There are 2 issues:

1. pc0 isn't specified.
2. -mpc80x should be an error.
