Summary: mingw-get: CVS build report for missing flex is inadequate

Initial Comment:
When building from CVS sources, flex is required to create pkginfo.c from pkginfo.l

configure checks for presence of flex, but does not abort when it is missing -- it substitutes the null command.  Thus, when make attempts to parse pkginfo.l, an empty pkginfo.c is created.  This results in link failure, due to missing symbols, later in the build; it isn't immediately obvious that the cause is missing flex.

Consider making configure more robust wrt flex checking, forcing an abort when pkginfo.c is not present in the source tree.
