rt/hare+libc.sc: include .rela.plt section for glibc ELF binaries

ld.bfd forgets to create a .rela.plt section for lazy references.
ld.bfd then shovels both immediate and lazy dynamic symbols in
a single .rela.dyn section.

glibc cannot handle different dynamic symbols in the same section
and throws the following error during program startup:
error while loading shared libraries:
unexpected PLT reloc type 0x08

ld.gold includes the missing section, and binaries work fine.
musl can handle both dynamic symbol types in the same section.

The fix is simple: explicitly include the missing section.
