fix configure's generation of settings file on ARM platform

This patch fixes generation of settings file on ARM platform
by configure script. This fixes build issue on ARM platform
where ghc-stage1 compiler is not able to read the target arch
value and due to this issue build fails with:

ghc-cabal: Failed to read "target arch" value "ArchARM ARMv7 [VFPv3, NEON]"
