Unfortunately, just adding -no-pie to GUEST_LDFLAGS does not help:
https://github.com/pevik/ltp/actions/runs/1965302083
/usr/bin/ld: bootstrap_x86_64.o: relocation R_X86_64_16 against symbol `kvm_gdt32_desc' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: -pie: error: PHDR segment not covered by LOAD segment
FYI slightly different OS failed on your original version, but that's probably
not interesting:
