Comment (by Joel Sherrill):

 This is needed on the 4.10 branch to build tools with GCC >= 4.3 but the
 option does not exist on older GCC's. Given that 4.3 is quite old, any
 recent distribution should be OK. But if someone updated on an old
 distribution with a gcc < 4.3, this option should not be present.

 Is there a clean way to make this CFLAGS="-fgnu89-inline" default to on
 but let someone disable it if they are still on an old distribution? They
 would be using a host OS which is completely unsupported since even CentOS
 6 had a gcc new enough.

 Chris? What would be the cleanest way to achieve this? We need to be able
 to build 4.10 on recent environments.
