I just discovered that someone has written a nice macro for this in the 
autoconf archive (http://ac-archive.sourceforge.net/, package 
autoconf-archive on my machine).

You would use it like this:

AC_CHECK_ICU(3.6, have_icu=true, have_icu=false)

if 3.6 is the minimum ICU version that it should check for. It runs 
icu-config and sets ICU_CFLAGS, ICU_CXXFLAGS, ICU_LIBS which can then be 
used in Makefile.am (as is already being done in harbuzz-ng).

This would be a direct replacement for the current 
PKG_CHECK_MODULES(ICU, icu, have_icu=true, have_icu=false). I don't know 
what the minimum version of ICU would be for harbuzz-ng, so I haven't 
submitted a patch.
