freetype/builds/unix/detect.mk
Werner Lemberg f83ded0174 FreeType 2 can now be built in an external directory with the
configure script also.

* builds/freetype.mk (INCLUDES): Add `OBJ_DIR'.

* builds/unix/detect.mk (have_mk): New variable to test for
external build.
(unix-def.mk): Defined according to value of `have_mk'.
* builds/unix/unix.mk (have_mk): New variable to test for
external build.
Select include paths for unix-def.mk and unix-cc.mk according
to value of `have_mk'.
* builds/unix/unix-def.in (OBJ_BUILD): New variable.
(DISTCLEAN): Use it.
* builds/unix/unix-cc.in (LIBTOOL): Define default value only
if not yet defined.
* builds/unix/install.mk (install): Use `OBJ_BUILD' for installing
freetype-config.

* configure: Don't depend on bash features.
(ft2_dir, abs_curr_dir, abs_ft2_dir): New variables (code
partially taken from Autoconf).
Build a dummy Makefile if not building in source tree.

* docs/INSTALL: Document it.
