libinkpost.a is supposed to contain files needed by subdirs, according to the comment. In particular, a few unit test programs in subdirectories link against libinkpost.a but not libinkpre.a. It seems useful to maintain this distinction: reduced link times, and it facilitates debugging of some link-related bugs (e.g. the recent mips problem) to have different executables link against different subsets of the .a files.

The attached patch moves gc-related files from libinkpre.a to libinkpost.a.

According to nm, the relevant two .o files (gc.o and gc-anchored.o) don't depend on any other object files, whereas very many files depend on gc-anchored.o, and many of the main-containing files depend on gc.o.
