Re: [PATCH 2/4] selftests/mm: pass down full CC and CFLAGS to check_config.sh

check_config.sh checks that liburing is available by running the compiler provided as its first argument. This makes two assumptions:

1. CC consists of only one word
2. No extra flag is required

Unfortunately, there are many situations where these assumptions don't hold. For instance:

• When using Clang, CC consists of multiple words
• When cross-compiling, extra flags may be required to allow the compiler to find headers

Remove these assumptions by passing down CC and CFLAGS as-is from the Makefile, so that the same command line is used as when actually building the tests.

Looks reasonable to me and I hope we find no surpirses :)
