  strtol, strtoll, strtoul, strtoull: Make ISO C 23 compliant.
  
  * lib/strtol.c (INTERNAL (strtol)): Treat 'b' and base 2 like 'x' and
  base 16. Based on glibc commit 64924422a99690d147a166b4de3103f3bf3eaf6c
  by Joseph Myers.
  * m4/strtol.m4 (gl_FUNC_STRTOL): Test also whether parsing binary
  integers works. Update cross-compilation guesses.
  * m4/strtoll.m4 (gl_FUNC_STRTOLL): Likewise.
  * m4/strtoul.m4 (gl_FUNC_STRTOUL): Likewise.
  * m4/strtoull.m4 (gl_FUNC_STRTOULL): Likewise.
  * tests/test-strtol.c (main): Add tests of parsing binary integers.
  * tests/test-strtoll.c (main): Likewise.
  * tests/test-strtoul.c (main): Likewise.
  * tests/test-strtoull.c (main): Likewise.
  * doc/posix-functions/strtol.texi: Mention the problem with parsing
  binary integers.
  * doc/posix-functions/strtoll.texi: Likewise.
  * doc/posix-functions/strtoul.texi: Likewise.
  * doc/posix-functions/strtoull.texi: Likewise.
