B: in-tree libraries that we might need (in case of ecpglib: libpq)
A: path to those in-tree libraries
D: external libraries that we might need (in case of ecpglib in my case:
-lcrypt -lm)
C: path to those external libraries (e.g., /usr/local/lib)
On the linker command line, we need this information in one of the
following two orders:
A B C D
A C B D
The Makefile.shlib receives from the respective main makefile "A B D" in
SHLIB_LINK and would have to insert "C" in the middle somewhere.
Currently, the actual behavior is "C A B D" and the failed patch wanted
to do "A B D C", both of which are wrong.
So either we code up some intelligence to put the "C" in the right
position or we have to pass down "A B" and "D" separately from the main
makefile.
