We add a 'make check' test that lints all Makefiles in the source directory of the glibc build. This linting test ensures that the lines in all Makefiles will be sorted correctly as developers creates patches. It is added to 'make check' because it is light-weight and supports the existing developer workflow The test adds ~3s to a 'make check' execution. No regressions on x86_64 and i686.
