Yes, thank you.  I'm just waiting for ffmpeg to baseline an embedded build.

Putting the PKG_CONFIG_PATH assignment before the configure helps configure find the pkgconfig files, but the data in the .pc files is still wrong, in that it has /usr as the prefix, rather than /work/usr.  I finally brute-forced it by adding a sed pass to fix the .pc files.

The current, apparently working, command lines are:

PKG_CONFIG_PATH=/work/usr/lib/pkgconfig ./configure --prefix=/usr
make
make prefix=/work/usr install
for F in /work/usr/lib/pkgconfig/*pc; \
  do sed -I -e 's/prefix=\/usr/s#/usr#/work/usr#' $F; done

These leave the programs and libraries expecting to load and run from /usr, as they will in the embedded system, but store them in /work/usr so they can be collected for the embedded system's disk image.

I do get some warnings from libtool, but the end result works.

Any idea how to get the values I need into the .pc files WITHOUT the sed?

Didn't know it existed, but it doesn't show any way to fix the .pc files, either.
