Remove empty generated file upon gperf failure
Prior to this change the build could fail as follows, if gperf is not
available (or fails):
- make(1) stops due to the gperf error, but an empty target file
(cfns.h) is still created
- the empty cfns.h is newer than the source cfns.gperf so it is not
regenerated on subsequent builds
- the gcc build fails (undefined reference to libc_name_p)
