What did you do?

when I use go build -asan.

What did you see happen?

it report "-asan is not supported with gcc compiler 0.0"
gcc -v looks like this:
gcc -v

使用内建 specs。

gcc 版本 8.4.1 20200928 

What did you expect to see?

that's because compilerVersion , Use of regular expressions is gcc version (\d+)\.(\d+) but, it couldn't pattern with 'gcc 版本 8.4.1 20200928 '

I think should change the regexp, if needed I would like to pull this pr.
