bfd: Stop using -Wstack-usage=262144 when built with Clang

Browse Source 
Some components of GNU Binutils will pass "-Wstack-usage=262144" when
"GCC >= 5.0" is detected.  However, Clang does not support "-Wstack-usage",
despite that related configuration part in bfd/warning.m4 handles the latest
Clang (15.0.0 as of this writing) as "GCC >= 5.0".

The option "-Wstack-usage" was ignored when the first version of Clang is
released but even this "ignoring" behavior is removed before Clang 4.0.0.
So, if we give Clang "-Wstack-usage=262144", it generates a warning, making
the build failure.

This commit checks "__clang__" macro to prevent adding the option if the
compiler is identified as Clang.

bfd/ChangeLog:

	* warning.m4: Stop appending "-Wstack-usage=262144" option when
	compiled with Clang.
	* configure: Regenerate.
