Comment (by eschnett):

 I have implemented this for zlib, one of the simpler external libraries.
 The implementation looks as follows:

 - the build instructions are taken out of configure.sh and moved to a new
 file build.sh
 - a new make variable BUILD_ZLIB remembers whether zlib is found on the
 system or needs to be built
 - make.code.deps states that the thorn depends onto the zlib library, if
 BUILD_ZLIB is set
 - make.code.deps defines how to build zlib, and calls build.sh

 This is too disruptive for the release. I will test this more, and propose
 a patch after the release.
