commit: https://git.buildroot.net/buildroot/commit/?id=bda95544b90af692fe9a33234caaa9f77b9a1e9e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Fixes the following security vulnerability:

- CVE-2019-19126: ld.so failed to ignore the LD_PREFER_MAP_32BIT_EXEC
  environment variable during program execution after a security
  transition, allowing local attackers to restrict the possible mapping
  addresses for loaded libraries and thus bypass ASLR for a setuid
  program.  Reported by Marcin Kościelnicki.
