Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Add libregex, connect it to the build libregex is a regex(3) implementation intended to feature GNU extensions and any other non-POSIX compliant extensions that are deemed worthy. These extensions are separated out into a separate library for the sake of not cluttering up libc further with them as well as not deteriorating the speed (or lack thereof) of the libc implementation. libregex is implemented as a build of the libc implementation with LIBREGEX defined to distinguish this from a libc build. The reasons for implementation like this are two-fold: 1.) Maintenance- This reduces the overhead induced by adding yet another regex implementation to base. 2.) Ease of use- Flipping on GNU extensions will be as simple as linking against libregex, and POSIX-compliant compilations can be guaranteed with a REG_POSIX cflag that should be ignored by libc/regex and disables extensions in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when implemented in this fashion. Tests are added for future functionality, but left disconnected for the time being while other testing is done.
