32-bit testsuite failures

Running the testsuite on my old 32-bit box, I get a lot of failures I don't get on my 64-bit box.

resourceLimit: The compiled ways consistently fail with

Wrong exit code (expected 0 , actual 1 )
Stdout:

Stderr:
resourceLimit: setResourceLimit: invalid argument (Invalid argument)

64 1-bits look as if some alignment broke.

ghcpkg01 and safePkg01: During the testsuite run, both fail with

Actual stderr output differs from expected:
...
+WARNING: cache is out of date: localXXX/package.cache
+  use 'ghc-pkg recache' to fix.

but when run on their own, both consistently pass. Since otherwise they behave as expected, it looks like a load-induced hiccough (which is a bit surprising because I ran the testsuite with THREADS=1, so there shouldn't be much going on to upset the tests).

Various recompilation-related failures: in tests/ghci, prog006, ghci.prog009, prog003, ghci027, 1914 all omit at least some recompilations and thus produce more or fewer error messages than expected resp. unexpected type info.

In tests/driver: recomp006 and T5147 fail with Wrong exit code (expected 0 , actual 2 ), both occasionally pass when run on their own; recomp001 doesn't produce the expected diagnostic, -C.hs:3:11: Module B' does not export foo', recomp009 produces the wrong stdout

In tests/ghc-api: apirecomp001 fails with

Wrong exit code (expected 0 , actual 2 )
Stdout:

Stderr:

myghc.hs:50:7: Not in scope: data constructor `RunFailed'

Last, the allocation figures for perf/compiler/T4801 haven't been adjusted for 32-bit systems, thus T4801 fails with

bytes allocated 231673896 is less than minimum allowed 330000000

I wouldn't like to set new limits myself without more data points.
