[PATCH] binutils-gdb/git: Handle *.ac and *.m4 files in .gitattributes

[Tom de Vries]

Since commit 52ca3d3fe61 ("toplevel: unify the GCC and GDB/binutils .editorconfig
files"), .editorconfig has settings for .ac and .m4 files:
...
[*.{ac,m4}]
indent_style = tab
indent_size = 2
trim_trailing_whitespace = true
...

There are no setting for those files in .gitattributes, so the whitespace
attribute defaults to trailing-space (shorthand for blank-at-eol,
blank-at-eof) and space-before-tab.

Since according to .editorconfig the indentation style is tab, add
indent-with-non-tab as well.

Since aclocal.m4 is generated, unset the whitespace attribute.  Likewise for
configure.

FWIW this seems fine to me.

I'll rubber-stamp this for the binutils side, but IMO there is no need
for a global gdb maintainer to wait for approval from binutils
maintainers for this shared file.

 Should this be documented in top-level MAINTAINERS?  Should this file be 
kept in sync with GCC?
