True, but this just can't be done without a significant effort. As
soon as you configure some package in the source tree, autoconf will
complain if you try to run configure on the same srcdir from a
different builddir, which is the case when configuring the target
library (unless I'm missing something; there appears to be some
soft-linking pass to work around this potential problem when
srcdir==builddir, but, IIRC, I've had trouble with it last time I
tried a srcdir==builddir build on some odd platform)
