Hi,

starting with version 3.5.5-1, the openssl package started to FTBFS on ppc64
due to the build system trying to link ELFv1 with ELFv2 code [1]:

${LDCMD:-gcc} -pthread -m64 -Wa,--noexecstack -Wall -fzero-call-used-regs=used-gpr -Wa,--noexecstack -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/openssl-3.5.5=. -fstack-protector-strong -Wformat -Werror=format-security  -Wl,-z,relro -Wl,-z,now \
	-o fuzz/ml-kem-test \
	fuzz/ml-kem-test-bin-fuzz_rand.o \
	fuzz/ml-kem-test-bin-ml-kem.o \
	fuzz/ml-kem-test-bin-test-corpus.o \
	libcrypto.a -lz -lzstd -ldl -pthread

collect2: error: ld returned 1 exit status

Most likely someone upstream assumed that PowerPC means ELFv2 these days, i.e.
the ABI used on ppc64el but that's obviously wrong.

Will also report this upstream.

Thanks,
Adrian
