Accept GHCRTS=-N1 when not compiled with -threaded
current behaviour:
> ghc Main.hs -o test
> ./test +RTS -N1
test: the flag -N1 requires the program to be built with -threaded
[blah blah]
requested:
> ghc Main.hs -o test
> ./test +RTS -N1
hello world
Motivation: In certain environments, threaded is bad idea due to resource constraints even when multiple capabilities are available, because resident memory can increase with parallel execution. Slapping GHCRTS=-N1 onto those environments would be nice, but breaks for things not compiled with -threaded.
