This is an auto-filled bug because media-libs/x264 fails to compile. The issue was originally discovered on arm64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info.

Globally set AS variable can point to GNU assembler (e.g. AS="${CHOST}-as") and this is not any misconfiguration. x264 build system has non-standard and architecture-dependent expectations about value of AS variable: In x264-0.0.20190903 in configure: ... case $host_cpu in i*86) ... AS="${AS-nasm}" ... ;; x86_64) ... AS="${AS-nasm}" ... powerpc*) ... if [ $asm = auto ] ; then ... AS="${AS-${CC}}" ... ;; ... mips*) ... AS="${AS-${CC}}" ... ;; arm*) ... if [ "$SYS" = MACOSX ] ; then AS="${AS-${CC}}" ... elif [ "$SYS" = WINDOWS ] && [ "$compiler" = CL ] ; then AS="${AS-${SRCPATH}/tools/gas-preprocessor.pl -arch arm -as-type armasm -force-thumb -- armasm -nologo -ignore 4509}" elif [ "$SYS" = WINDOWS ] ; then AS="${AS-${SRCPATH}/tools/gas-preprocessor.pl -arch arm -as-type clang -force-thumb -- ${CC} -mimplicit-it=always}" else AS="${AS-${CC}}" fi ;; aarch64) ... if [ "$SYS" = MACOSX ] ; then AS="${AS-${CC}}" ... elif [ "$SYS" = WINDOWS ] && [ "$compiler" = CL ] ; then AS="${AS-${SRCPATH}/tools/gas-preprocessor.pl -arch aarch64 -as-type armasm -- armasm64 -nologo}" else AS="${AS-${CC}}" fi ;; ... Therefore the easiest solution is to set AS="nasm" on x86_{32,64} and AS="${CC}" on other architectures.
