Now I'm really confused

GHC's heap exhausted;
while trying to allocate 0 bytes in a 15998976-byte heap;
use the `-H<size>' option to increase the total heap size.

This is the same ghc which successfully compiled itself twice before.
It's now compiling a slightly newer version of itself.

Why the -H option set the *maximum* heap size?!

Should "SRC_HC_OPTS += -H16M" be removed from ghc/compiler/Makefile?
A good product shouldn't need explicit hints about the amount memory
it's going to use!

BTW, here are reasons for confusion of -H and -M: the error message
talks about -H, and ghc itself has a -H shortcut (instead of +RTS -H)
but no -M shortcut (requires +RTS -M).
