* 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

* DWARF-5 is now used by default with gcc-11, causing
11.1.0/ld: internal error in format_file_lineno, at ../../gold/dwarf_reader.cc:2278
collect2: error: ld returned 1 exit status
in various projects (runc-opencontainers, libhybris, collada-dom)
* https://gcc.gnu.org/gcc-11/changes.html
For targets that produce DWARF debugging information GCC now defaults to DWARF version 5
(with the exception of VxWorks and Darwin/Mac OS X which default to version 2 and
AIX which defaults to version 4). This can produce up to 25% more compact debug
information compared to earlier versions.
To take full advantage of DWARF version 5 GCC needs to be build against binutils version 2.35.2 or higher.
When GCC is build against earlier versions of binutils GCC will still emit DWARF version 5 for
most debuginfo data, but will generate version 4 debug line tables (even when explicitly given -gdwarf-5).
The following debug information consumers can process DWARF version 5:
GDB 8.0, or higher
valgrind 3.17.0
elfutils 0.172, or higher (for use with systemtap, dwarves/pahole, perf and libabigail)
dwz 0.14
Programs embedding libbacktrace are urged to upgrade to the version shipping with GCC 11.
To make GCC 11 generate an older DWARF version use -g together with -gdwarf-2, -gdwarf-3 or -gdwarf-4.

Since GCC 11 will switch to dwarf-5 as default, this patch will be
required soon

If BRANCH is defined in local.conf then that name is used to d/l sources
for binutils. You will get this error:
Fetcher failure for URL: 'git://sourceware.org/git/binutils-gdb.git;branch=hardknott;protocol=git'. Unable to fetch URL from any source.
Rename to SRCBRANCH like glibc has to avoid the more common variable name BRANCH.
