Bug ID: 57339
           Summary: can't run winegcc hello world program (clang/musl
                    environment)
           Product: Wine
           Version: 9.20
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winelib
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

simple c hello world built with winelib immediately crashes with a page fault.
i am running this under a musl libc environment with clang as a c compiler.
wine itself is also built under that environment and works fine, so it's
possible the wine build system is passing something something i'm not.

winegcc -o hello.exe hello.c -b x86_64-windows --verbose -Wb,--verbose

seemingly, when adding the `-b x86_64-windows` flag to winegcc, the result is a
PE executable that does run fine, unlike the previous result which was an
.exe.so shared library alongside a .exe shell wrapper. i attach the verbose
output of this invocation

passing -fuse-ld=bfd to winegcc fixes all the issues, so this seems to be a
problem with clang's lld linker
