In PRs #2444 we added the workaround-ghc-mmap-crash flag on some of our packages. That flag added `-with-rtsopts=-xm20000000` to some of our binaries. But other binaries would occasionally still trigger the mmap bug, most importantly ghc itself. This commit undoes the previous way of applying the workaround and applies the same `-xm20000000` RTS option everywhere via the GHCRTS environment variable. But for this to work we have to link all binaries with the `-rtsopts` flag, otherwise they'll error out that the GHCRTS contains unsupported options.
They use custom setups and it is seemingly impossible to get them to link with anything other than the default -rtsopts=some Making them always throw an error when GHCRTS="-xm..."
So we don't have to deal the mmap errors on CI

This commit undoes the previous way of applying the workaround and
applies the same
-xm20000000RTS option everywherevia the GHCRTS environment variable.
But for this to work we have to link all binaries with the
-rtsoptsflag, otherwise they'll just ignore the GHCRTS.
Unfortunately this is impossible for custom setups, like used by
clash-cosimandclash-ffi-example.Therefor we clear the
GHCRTSvariable when building just those packages. And hope we don't hit the mmap issue while building those.Still TODO:
