binutils: backport gold changes to use mallinfo2 instead of deprecated mallinfojansa/binutils

* mallinfo got deprecacted in glibc-2.33 with:
  https://sourceware.org/git/?p=glibc.git;a=commit;h=e3960d1c57e57f33e0e846d615788f4ede73b945
  https://sourceware.org/git/?p=glibc.git;a=commit;h=30e5069c7d4b51288d3e6f75f53a6ad2f5e71b0f
* resolves this warning:
  oe-core$ grep mallinfo tmp-glibc/work/x86_64-linux/binutils-cross-x86_64/2.36.1-r0/temp/log.do_compile
  checking whether sbrk is declared... checking for mallinfo... yes
  ../../gold/main.cc:294:36: warning: ‘mallinfo mallinfo()’ is deprecated [-Wdeprecated-declarations]
* after:
  oe-core$ grep mallinfo tmp-glibc/work/x86_64-linux/binutils-cross-x86_64/2.36.1-r0/temp/log.do_compile
  checking for struct stat.st_mtim.tv_nsec in sys/stat.h... checking for mallinfo... yes
  checking whether snprintf is declared... checking for mallinfo2... configure: updating cache ./config.cache

  the configure output is badly mixed together, but mallinfo2 support was detected OK:
  oe-core$ grep _mallinfo tmp-glibc/work/x86_64-linux/binutils-cross-x86_64/2.36.1-r0/git/build.x86_64-linux.x86_64-oe-linux/gold/config.log
  ac_cv_func_mallinfo2=yes
  ac_cv_func_mallinfo=yes
