 HAVE_LD_DEAD_CODE_DATA_ELIMINATION"

Thanks, I reproduce the link error with toolchain
gcc version 9.3.0
GNU ld (GNU Binutils) 2.33.1

with same gcc version, just upgrading ld version to 2.36.1, it does not 
segfault and build completes. there should be bugs in low version of ld,
and the ".reloc  .text, R_ARM_NONE, ." triggers that.
