Can only reproduce with gcc:14, albeit no idea what's going on here. (it does bundle embree at src/3rdparty/embree) I've tried some combinations of C{,XX}FLAGS flags and this seems to be caused by -march=native (or in my case, -march=znver2)?
make.conf fragment:
# COMMON_FLAGS="-O3 -march=znver2 -pipe -ggdb3" # original, bad
# COMMON_FLAGS="" # 1. good
# COMMON_FLAGS="-O3" # 2. good
# COMMON_FLAGS="-O3 -march=znver2" # 3. bad
# COMMON_FLAGS="-O3 -pipe" # 4. good
COMMON_FLAGS="-O3 -pipe -ggdb3" # 5. good
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS} -D_GLIBCXX_ASSERTIONS"
gcc version:
gcc version 14.0.1 20240124 (experimental) 3de031c96f28f19a68ea2080260d8fd2c78828ee (Gentoo 14.0.1 p, commit ddeac849ac4c3fecdf591ab6fb075cc6c5afdbff)

Just a guess given haven't really looked at this yet, but if it's related to -mavx then I'd suspect [1] and [2] being related. [1] is probably missing something with gcc:14 or something like that.
