description:
tests/lint: allow skipping individual tests

Depending on the platform, some tests do not make sense or produce
platform-dependent results.  Allow these tests to be marked as such.

For example, the test lex_integer.c only works on 64-bit platforms.
Therefore it is disabled on i386 for now since it prints different
warnings there.  Even better would be a "lint1-only-on-lpi32" toggle,
but that would need detection of 'sizeof(int)' at runtime.
