[Bug 19009] New: Crosstests don't compile with CROSSCC="ccache i586-mingw32msvc-gcc"

http://bugs.winehq.org/show_bug.cgi?id=19009

Summary: Crosstests don't compile with CROSSCC="ccache
                    i586-mingw32msvc-gcc"
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: build-env
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The culprit is the line AC_SUBST(CROSSTARGETFLAGS,"-b `expr $CROSSCC :
'(.*)-gcc'`") in configure.ac that doesn't handle multiple words in the
CROSSCC variable.

Unfortunately I wasn't able to find a way to fix this one.
