+#undef linux
fix armadillo macro expansions (#5268) * fix armadillo macro expansions - most compilers `#define linux 1` - armadillo does raw pasting of include directories in code - this means macro expansion of `linux-x86_64` -> `1-x86_64` - new version, previous download url seems broken - lib64 instead of lib? - needs verification, was required for intel, works for others * flake8: two spaces is modules, one for classes * add some explanation of how the patch works * use p1 patch file with -U0 to prepend undef linux * armadillo v8.100.1 2017-09-11 10:04:02 +08:00			`--- a/include/armadillo_bits/compiler_setup.hpp`
