I have observed this many times now that the compilation stops at linking stage.
First it happened a few times during compiling the ghc libraries, while creating the wasm-cross nixpkgs (this was very annoying, as I had to restart the whole process again)
And this behavior can be easily reproduced while running the ghc testsuite. The compilation stops at the linking stage for random testcases. On recompiling / retrying it mostly works fine.
Here is a simple testsuite runner I created to run the ghc testsuite.

The occurence of this issue is particularly high with this, like 10% -20 % test cases.
/nix/store/nmpgb5chlsxb6jdjwl70vqa8wbms3mly-llvm-binutils-7.0.0/bin/wasm32-unknown-unknown-wasm-ld: warning: function signature mismatch: fprintCCS_stderr
>>> defined as (I32, I32, I32) -> void in Profiling.p_o
>>> defined as (I32) -> void in PrimOps.p_o
This is our last signature mismatch!!
Just opening an issue for something we've known about for a couple weeks now. Binary sizes are on the order of 100M, which is clearly absurd. @dfordivam thinks this is due to a lack of DCE. This problem is present both with the wasm backend and the native unregisterised backend, so maybe this should be an issue on GHC trac.
As for solutions, it seems reasonable that we could implement some kind of DCE despite the trampolining the C code does. But another idea we had was to switch to the LLVM backend before wasm has tail calls. We could write an implementation for the GHC calling convention (ghccc) that lowers calls into a trampoline ABI. If we enable LTO in LLVM, we might get DCE in the linker before lowering out of bitcode, just based on the ghccc calls.
For this code (from bytestring) clang gives error
foreign import ccall unsafe "static stdlib.h &free" c_free_finalizer
:: FunPtr (Ptr Word8 -> IO ())
./ghc25458_0/ghc_4.hc:153:42: error: use of undeclared identifier 'free'
(W_)&base_GHCziPtr_FunPtr_con_info, (W_)&free
It is solved by adding the appropriate includes in ghc_4.hc
#include <stdlib.h>
mkdir tmp
ghc -c csrc/code.c -outputdir tmp/
# This works fine, creates tmp/csrc/code.o
wasm32-unknown-unknown-wasm-ghc -c csrc/code.c -outputdir tmp/
error: unable to open output file 'tmp/csrc/code.o': 'No such file or directory'
Due to this cannot compile cabal projects with c-sources.
With Stage1Only flag stage2 is still built...
# You may wonder why Stage1Only=YES still builds compiler/stage2. Quoting # simonmar in #7639:
#
# "strictly speaking building compiler/stage2 is correct, because it is
# the ghc package that can be used with [ghc-stage1]. If you don't
# want to build it, then setting stage=1 in your mk/build.mk should
# disable it."
