package/opencv: fix build with old glibc versions
Prior to glibc 2.18, definitions like SIZE_MAX or INT_FAST32_MAX from
<stdint.h> were only made available for C code, or in C++ if
__STDC_LIMIT_MACROS was defined.
The code from jasper uses such definitions, without defining
__STDC_LIMIT_MACROS. Unfortunately, defining __STDC_LIMIT_MACROS in
the jasper headers doesn't work, since <stdint.h> has already been
included before, at a point where __STDC_LIMIT_MACROS was not defined.
So to solve this problem, we simply pass -D__STDC_LIMIT_MACROS in
CXXFLAGS when building opencv with jasper support.
This patch uses the same solution used for libraw:
