[Buildroot] [PATCH] lsof, m4: use variables from BR instead of uClibc

[Markus Heidelberg]

UCLIB_HAS_* is not defined in Buildroot space, so the conditions always
evaluate to the same result. Use appropriate Buildroot variables.
---

Note: This change is untested and m4 still uses UCLIBC_HAS_REGEX, where I
don't know how to handle it.
