[Buildroot] [PATCH] package/xterm: Avoid freetype2 path poisoning using imake

[Valentin Korenblit]

When imake is installed on the host, it tries to include
freetype headers from host, so we must override ac_cv_path_IMAKE
to avoid this.

Extract from config.log:

configure:14803: checking if we should use imake to help
configure:14820: result: yes
configure:14829: checking for xmkmf
configure:14846: found /usr/bin/xmkmf
configure:14857: result: /usr/bin/xmkmf
configure:14920: testing Using /usr/bin/xmkmf  ...
configure:15015: testing IMAKE_CFLAGS  -I. -I/usr/include/freetype2
