Hello
This is more generalized way to give a user the ability to override
the generation of target libraries, that are enabled per default.
For example with the configure switch --disable-target-zlib,
target-zlib is added to the script variable noconfigdirs and this
target library will not be built.
regards
Thomas
PS.
If it helps. I've already done copyright assignment for future changes.
But, not explicit for the configure scripts.
Also I don't have write permission, (nor I'm requesting for this).
