[CMAKE] CYGWIN: set correct binfmt and abi

Browse Source 
Compiling on CYGWIN prints this error:

[  4%] Building ASM-ATT object libs/context/CMakeFiles/boost_context.dir/src/asm/make_x86_64_sysv_elf_gas.S.o
/usr/bin/as: unrecognized option `-x'
make[2]: *** [libs/context/CMakeFiles/boost_context.dir/build.make:78: libs/context/CMakeFiles/boost_context.dir/src/asm/make_x86_64_sysv_elf_gas.S.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:3961: libs/context/CMakeFiles/boost_context.dir/all] Error 2
make: *** [Makefile:156: all] Error 2

This PR fixes the right assembly sources to build because sysv and elf are nonsense on CYGWIN.
After this patch, it correctly searches make_x86_64_ms_pe_gas.asm, although it still raises an error because unrecognized -x option.
