build: allow a forcing build with "broken" regex.

Browse Source 
The configure would fail when cross compiling due to the regex check
automatically failing for cross compilation. Since you can't run the
regex binary check, assuming the regex library on the target platform is
working would be the only way to get the build working, or adding a
force for people to control based on their build environment.
