[Bug 15883] When the Linux version of SDL_mixer is installed, programs in Qb64 fail to compile (c++ compilation failed).

Qb64 bundles gnu ld.exe which is where the bug is occuring.

The problem occurs when ld.exe searches its library search path for any of
SDL_mixer, SDL_ttf, SDL_image and so on, it tries "/usr/lib/libSDL_ttf.a", wine
seems to guess that this is a unix path and shouldn't bother trying
"C:\usr\lib\libSDL_ttf.a"

This snippet of a trace when compiling samples/audio.bas shows that Wine finds
that /usr/lib/libSDL_ttf.a is on Z: and CreateFileW succeeds.

trace:file:CreateFileW L"/usr/lib/libSDL_ttf.a" GENERIC_READ FILE_SHARE_READ
FILE_SHARE_WRITE  creation 3 attributes 0x80
trace:file:RtlDosPathNameToNtPathName_U
(L"/usr/lib/libSDL_ttf.a",0x6afb10,(nil),(nil))
trace:file:RtlGetFullPathName_U (L"/usr/lib/libSDL_ttf.a" 520 0x6af854 (nil))
trace:file:find_drive_rootW L"/usr/lib/libSDL_ttf.a" -> drive Z:, root="/",
name=L"/usr/lib/libSDL_ttf.a"
trace:file:wine_nt_to_unix_file_name L"\??\Z:\usr\lib\libSDL_ttf.a" ->
"/home/jeffz/.wine/dosdevices/z:/usr/lib/libSDL_ttf.a"

commenting out the "if (name[0] == '/')  /* may be a Unix path */" block in
ntdll/path.c makes ld.exe work and so Qb64 then works, but breaks handling unix
paths.
