The other patch removes the compilation of backend/lib/qsort.c, as
qsort() is a standard function in stdlib.h and can be used any

backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c,
and backend/storage/page/bufpage.c

There's more to come. Please review these patches. I ran the
regression tests and they only failed where this was expected
(random, geo, etc).
