yes, the same is on my branch. A problem is exposed after my commit
  commit 7ed43415380ec6270e53c0ed3f42e5cb99df1f6e

        * x86_64-tcc: use /usr/lib64,.. instead of /usr/lib,..
        * don't set tcc_lddir="lib64" if cpu="x86"

--- a/configure

     if test x"$bindir" = x""; then
-    if test x"$tccdir" = x""; then
-    tccdir="tcc"
-    fi
     if test x"$docdir" = x""; then

Then the right fix must be
-     docdir="${sharedir}/doc/${tccdir}"
+    docdir="${sharedir}/doc/tcc"

I'm trying to do that, i.e MSYS2 unix. A big issue is not to define
_WIN32 which assume standalone mingw (tcc headers/libraries in
C:\Program Files\tcc) w/o MSYS2. mingw on MSYS2 can be different too
because there is all headers and libraries already present.

Executable names:

Mingw on MSYS2 or standalone tcc installation:

By default target will be selected depending on msys2 shell
environment (MSYS2 or Mingw on MSYS2).
