In general it is possible to cross-compile from any host for any
target that is supported by tcc.

To build and use an arm-eabihf-tcc, for example:

  $ ./configure
  $ make cross-arm-eabihf
  $ sudo make install

  $ arm-eabihf-tcc -v hello.c

Of course, the cross-compiler needs to know where to find the header
files, crtX.o's and libraries for that target.  It might work out of
the box if those files are present in /usr/arm-linux-gnueabihf for
example.  Otherwise it is possible to create a "config-extra.mak"
manually.  See "$ make help".

The commit comment here shows how a cross-compiler for android-armeabi-v7a
can be made on windows (as well as on any other host).
