Remove "for the Ada runtime" here. It's also used for SJLJ in C++ on 32-bit
Windows for example (unless DONT_USE_BUILTIN_SETJMP is defined). See the
internal manual, 18.20.9 Assembler Commands for Exception Regions:
-- Macro: DONT_USE_BUILTIN_SETJMP
Define this macro to 1 if the 'setjmp'/'longjmp'-based scheme
should use the 'setjmp'/'longjmp' functions from the C library
instead of the '__builtin_setjmp'/'__builtin_longjmp' machinery.
