[PyQt] SIP cross compile LINK macro not working properly

I am trying to compile SIP in Yocto and for that I use a cross compiler. To
tell sip configure that I wanna use another toolchain I use the CC, CXX and
LINK macros.

For some reason the LINK macro is not propogated all the way through to the
siplib Makefile. Does anyone know why?

$ python configure.py CC=mygcc CXX=myg++ LINK=myg++
This is SIP 4.19 for Python 2.7.12 on linux2.
The SIP code generator will be installed in /usr/bin.
The sip module will be installed in /usr/lib/python2.7/dist-packages.
The sip.pyi stub file will be installed in /usr/lib/python2.7/dist-packages.
The sip.h header file will be installed in /usr/include/python2.7.
The default directory to install .sip files in is /usr/share/sip.

CC = mygcc

LINK = g++  <----------------------------------------- Why?
CPPFLAGS = -DNDEBUG -I. -I/usr/include/python2.7
CFLAGS = -pipe -fPIC -O2 -Wall -W
CXXFLAGS = -pipe -fPIC -O2 -Wall -W
