[Ffmpeg-devel] bash substitutions

[Jacob Meuser]

revision 1.217 of configure added some shell substitutions.
these apparently only work with bash, which is _not_ the /bin/sh
on all systems.

specifically:

  echo "SPPMAJOR=${lavc_version/.*/}" >> config.mak
  echo "LAVCMAJOR=${lavc_version/.*/}" >> config.mak
  echo "LAVFMAJOR=${lavf_version/.*/}" >> config.mak
  echo "LAVUMAJOR=${lavu_version/.*/}" >> config.mak

this not work with pdksh, which is the /bin/sh on OpenBSD.
I doubt it works with ash, which is the /bin/sh on NetBSD.

I suggest the following patch.
