If I build with hadrian using "quickest" setting I get a more reasonable number:
$ nm ./_build/stage1/bin/ghc | wc -l
102174
It'd be good to have these symbols in make-generated stage 2 executables too.

Does anyone know why I get so little symbols in stage 2 compiler compared to programs built with the same stage 2 compiler?
This is the build.mk I'm using
BuildFlavour = quick
ifneq "$(BuildFlavour)" "" include mk/flavours/$(BuildFlavour).mk endif
GhcRtsHcOpts += -O0 -g3 GhcStage2HcOpts += -debug -g5 GhcLibHcOpts += -g5
GhcThreaded = NO
BUILD_PROF_LIBS = NO
HADDOCK_DOCS = NO BUILD_SPHINX_HTML = NO BUILD_SPHINX_PDF = NO BUILD_MAN = NO
STRIP_CMD = :
Symbols in stage 2 compiler built with this build.mk:
$ nm /home/omer/haskell/ghc/inplace/lib/bin/ghc-stage2 | wc -l 9202
If I build `main = return ()` with the same compiler:
$ cat test.hs main = return ()
$ /home/omer/haskell/ghc/inplace/bin/ghc-stage2 -g5 -O0 test -fforce-recomp [1 of 1] Compiling Main ( test.hs, test.o ) Linking test ...
$ nm test | wc -l 35266
So it seems like a lot of symbols in the libraries are missing in the stage 2 executable.
I tried setting `DYNAMIC_GHC_PROGRAMS = NO` but I got even less number of symbols in the stage 2 compiler.
I also confirmed this using a debugger program I wrote which can find info table labels of objects in the heap when I run it on `test.hs` above but not when I run it on the stage 2 executable.
