bfd: Stop using -Wstack-usage=262144 when built with Clang
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. binutils/ChangeLog: * configure: Regenerate. gas/ChangeLog: * configure: Regenerate. gold/ChangeLog: * configure: Regenerate. gprof/ChangeLog: * configure: Regenerate. ld/ChangeLog: * configure: Regenerate. opcodes/ChangeLog: * configure: Regenerate.
