commit: https://git.buildroot.net/buildroot/commit/?id=8addf4b71eafc55e5f5c4c8828ad892799444169
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Fixes:

  .../x86_64-buildroot-linux-gnu/bin/ld: .../host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libtomcrypt.a(md5.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

when building a shared library that links with libtomcrypt. Our only
internal user dropbear doesn't do this, so there are no autobuilder
failures.
