Bug#927456: irrlicht makefiles does not honors CFLAGS and CXXFLAGS, so neither hardening

[PICCORO McKAY Lenz]

Package: libirrlicht-dev
Version: 1.5+dfsg1-1
Severity: serious

in Makefile line 84 we have a non override CFLAG set  as:

irrlicht-1.8.4.0/source/Irrlicht/Makefile

CFLAGS := -O3 -fexpensive-optimizations -DPNG_THREAD_UNSAFE_OK
-DPNG_NO_MMX_CODE -DPNG_NO_MNG_FEATUR
ES

so i set to serious due irrlicht on Debian uses system PNG and JPEG
libraries.. so here we can see more that just only not honor the CFLAGS..
take a shot to the "NO_MMX_CODE"
