MSYS: unrecognized option '--hash-style=gnu'

[mahaase]

First things first: Thanks for the fix: BobBuildTool/bob#395 👍

now there is a problem with the basement: unrecognized option '--hash-style=gnu'

basement/default.yaml

Line 43 in 52ea909

LDFLAGS: "-Wl,-O1 -Wl,--hash-style=gnu"

CMake Error at C:/msys64/home/mhaase/ws/fdt.bobrecipes/dev/dist/devel/win/cmake/1/workspace/usr/share/cmake-3.17/Modules/CMakeTestCCompiler.cmake:60 (message):
  The C compiler

    "C:/msys64/usr/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:

with that fix, the MSYS2 host-toolchain is working correctly in my environment! so i could remove many workarounds in my recipes.

MSYS has no hash tables, so this option isn't compiled into the linker and not available. (the MSYS guys explained that to me.)
