#62490: ruby27: universal build is incorrect
------------------------+----------------------

 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.99
 Keywords:              |       Port:  ruby27
------------------------+----------------------
 ruby27 installs with the universal variant, but what is installed is
 wrong, which causes other ports that use ruby27 to fail to build.

 This is a regression; ruby26 universal is fine.

 In ruby26, the file /opt/local/include/ruby-2.6.0/universal-
 darwin17/ruby/config.h contains for example:

 {{{
 #if defined(__ILP32__) || defined(__ILP32) || defined(_ILP32) ||
 defined(ILP32)
 #define SIZEOF_LONG 4
 #elif defined(__LP64__) || defined(__LP64) || defined(_LP64) ||
 defined(LP64)
 #define SIZEOF_LONG 8
 #endif
 }}}

 This is correct (or at least it allows other ports using ruby26 to build
 and it looks plausible although I don't know where `__ILP32__` or
 `__ILP32` or `_ILP32` or `ILP32` would be defined -- they are not standard
 defines that I'm aware of, whereas `__LP64__` and `_LP64` are both
 standard defines defined by clang in 64-bit mode). But in ruby27 the file
 /opt/local/include/ruby-2.7.0/x86_64-darwin17/ruby/config.h contains only:

 {{{
 #define SIZEOF_LONG 8
 }}}

 This is right for x86_64 but wrong for i386, hence when I try to build
 something that requires ruby27 (and I am building it universal) the build
 fails with:

 {{{

 }}}
