   4 Subject: [PATCH] setup.py: do not add invalid header locations
   5
   6 This piece of code incorrectly adds /usr/include to
   7 self.compiler.include_dirs, and results in the following invalid
   8 compilation line:
   9
  10 /home/thomas/projets/buildroot/output/host/usr/bin/arm-none-linux-gnueabi-gcc
  11   -fPIC -Wno-unused-result -Werror=declaration-after-statement -DNDEBUG -g
  12   -O3 -Wall -Wstrict-prototypes -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
  13   -D_FILE_OFFSET_BITS=64 -pipe -Os
  14   -I./Include -I/usr/include -I. -IInclude
  15   -I/home/thomas/projets/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include
  16   -I/home/thomas/projets/buildroot/output/build/python3-3.4.0b1/Include
  17   -I/home/thomas/projets/buildroot/output/build/python3-3.4.0b1
  18   -c /home/thomas/projets/buildroot/output/build/python3-3.4.0b1/Modules/_struct.c
  19   -o build/temp.linux-arm-3.4/home/thomas/projets/buildroot/output/build/python3-3.4.0b1/Modules/_struct.o
  20 cc1: warning: include location "/usr/include" is unsafe for cross-compilation [-Wpoison-system-directories]
  21
  22 The -I/usr/include is wrong when cross compiling, so we disable adding
  23 INCLUDEDIR and LIBDIR from the host when cross compiling.
