Apparently,

$ strings /Library/Frameworks/GHC.framework/Versions/Current/usr/lib/ghc-7.10.3/rts/libHSrts.a | grep gcc
...
/usr/local/Cellar/gcc/5.2.0/lib/gcc/5/gcc/x86_64-apple-darwin15.0.0/5.2.0/include
...

This resolves

$ brew tap homebrew/versions
$ brew install homebrew/versions/gcc5
$ ls /usr/local/lib/gcc/5/libgcc_s.1.dylib
/usr/local/lib/gcc/5/libgcc_s.1.dylib

I needed to change "brew install homebrew/versions/gcc5" to
"brew install homebrew/versions/gcc@5" for my version.

Output of "brew --version"
