Can't build lang/perl5.32. I have many vms running perl5.32 and they're not seeing any issues.
There's nothing in bugs suggesting there's an issue with this port right now.

The context is 14.0-CURRENT #0 main-n252119-dfa5a74357f amd64 1400046 1400046 with a nodebug kernel.
The sources were built with these (/etc/src.conf):

KERNCONF=RYZEN5
WITH_CCACHE_BUILD="TRUE"
CCACHE_PREFIX=/usr/local/bin
CPUTYPE?=znver3 
TARGET_CPU_ARCH=znver3
WITH_MALLOC_PRODUCTION= 
WITH_LLVM_TARGET_ALL=
WITH_LLVM_BINUTILS=
WITH_KERNEL_RETPOLINE=
#
WITH_PIE=yes
WITH_BIND_NOW=yes
WITH_RETPOLINE=yes
WITH_SSP=yes
#
WITH_OPENSSL_KTLS=

I'm going to try building a new world next, this time with no /etc/src.conf, or a minimal one.

But for now, I'm seeing unexpected failures with ports that compile fine on other systems:

1. portstree last updated: Tue Jan 4 17:03:38 2022 +0100 version: 570114
2. no /etc/make.conf
3. in /usr/ports/lang/perl5.32:
    [i] make clean && make distclean && make rmconfig && make rmconfig-recursive
    [ii] make MAKE_JOBS_UNSAFE=yes -j1 fails here:
