Should binutils require at least C99?

[Alan Modra]

I feel that it is reasonable nowadays to require a C99 compiler and
library to build binutils.  Trying to support older systems that no
one appears to test is a losing battle anyway.  For example, the s12z
target requires stdbool.h and stdint.h, and many targets include
string.h without concern for HAVE_STRING_H or STRING_WITH_STRINGS.

Does anyone object to formally dropping support for pre-C99?
