Subject: Update symbolic links to sources during make.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=755dbfe700494e3e34a0f282b399471d12be45cc;p=comedi.git

Update symbolic links to sources during make.

When building outside the source directory, recreate any symbolic links
to the sources if they are broken or pointing to the wrong files.
