Subject: [PATCH] kunit: kunit_config: Fix parsing of CONFIG options with space

Commit 8b59cd81dc5e ("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.

Maybe it would have been sufficient to just use
CONFIG_PATTERN = r'^CONFIG_(\w+)=(.*)$' instead?
