ExtUtils::Mkbootstrap - make a bootstrap file for use by DynaLoader

Mkbootstrap typically gets called from an extension Makefile.
There is no "*.bs" file supplied with the extension. Instead, there may
be a *_BS file which has code for the special cases, like posix for
berkeley db on the NeXT.
This file will get parsed, and produce a maybe empty
@DynaLoader::dl_resolve_using array for the current architecture. That
will be extended by $BSLOADLIBS, which was computed by
EExxttUUttiillss::::LLiibblliisstt::::eexxtt(()). If this array still is empty, we do nothing,
else we write a .bs file with an @DynaLoader::dl_resolve_using array.
The *_BS file can put some code into the generated "*.bs" file by placing
it in $bscode. This is a handy 'escape' mechanism that may prove useful
in complex situations.
If @DynaLoader::dl_resolve_using contains "-L*" or "-l*" entries then
Mkbootstrap will automatically add a ddll__ffiinnddffiillee(()) call to the generated
"*.bs" file.
