Small update: masking dev-libs/libgcrypt-1.9.4 so dev-libs/libgcrypt-1.8.8 is installed instead works fine for me on ppc64le
I can build it just fine on non-prefix system, both stable and unstable ppc64le. with USE=asm ofc probably something prefix-specific after all, maybe some host header leaking in.
actually reproduced now. I usually build with -mcpu=power9 if you have that in CFLAGS it'll build fine. but without specifying this it will fail. looks like it requires at least power8 crypto and some definitions to build properly.

while my fix solves issue partially, you still need to pass proper -mcpu in CFLAGS this code will compile with -mcpu=power8 and later. upstream enables power8 crypto but does not check if __POWER8_VECTOR__ is defined, which is required to build this code. also install app-portage/cpuid2cpuflags and configure CPU_FLAGS_PPC properly, otherwise you may be missing vector optimizations for power9 flags will look like this: > cat /etc/portage/package.use/50-cpu_flags.conf > */* altivec > */* CPU_FLAGS_PPC: altivec vsx vsx2 vsx3

another issue I've noticed in your build log. you seem to have empty CFLAGS, not only for -mcpu but for -O2 too is missing for example. real trigger for this bug is absence of at least -O1 parameter, maybe -Os will do. default is -O2. set that too. a lot of software does not really build with optimizations turned off or produces horrible code. I would check other software you've installed, maybe you've been missing those flags for a while.

The "emerge --info" output shows that CFLAGS *is* set though?
