Commit8b59cd81dc("kbuild: ensure full rebuild when the compiler is updated") introduced a new CONFIG option CONFIG_CC_VERSION_TEXT. On my system, this is set to "gcc (GCC) 10.1.0" which breaks KUnit config parsing which did not like the spaces in the string. Fix this by updating the regex to allow strings containing spaces.
