That's the sort of thing that would best be tested with 
build-many-glibcs.py to see if any configurations are using <endian.h> 
(possibly indirectly) in assembly source at present.  It appears the 
original addition of that check was because of a use in SH strlen.S, which 
was removed in commit 3ce2865f93d42f4721d58088dd6ab1dac06ea85b "SH: 
Replace <endian.h> usage with pre-processor macros.", but maybe there are 
other places still relying on it in assembly source.
