This issue wasn't caused by gcc upgrade, it was caused by:
https://patchwork.openembedded.org/patch/150269/
which was included in the same batch of updates when I've included
these RFT changes.

I've sent separate fix for perf with slightly longer explanation what
was wrong:
https://patchwork.openembedded.org/patch/151017/

Now I got a bit further with testing again, remaining 3 issues in public
recipes:

gcc-sanitizers/8.1.0-r0 fails to build with qemuarm (with thumb
enabled):
{standard input}: Assembler messages:
{standard input}:5724: Error: lo register required -- `ldr ip,[sp],#8'
make[2]: *** [sanitizer_linux.lo] Error 1

qtbase/5.6.3+gitAUTOINC+e6f8b072d2-r0 fails to build with qemuarm (with
thumb
enabled):
{standard input}: Assembler messages:
{standard input}: Error: unaligned opcodes detected in executable segment
make[2]: *** [.obj/qdrawhelper.o] Error 1

lib32-glibc-initial/2.27-r0 fails to build with multilib
checking installed Linux kernel header files... missing or too old!
configure: error: GNU libc requires kernel header files from
Linux 3.2.0 or later to be installed before configuring.
The kernel header files are found usually in /usr/include/asm and
/usr/include/linux; make sure these directories use files from
Linux 3.2.0 or later.  This check uses <linux/version.h>, so
make sure that file was built correctly when installing the kernel header
files.  To use kernel headers not from /usr/include/linux, use the
configure option --with-headers.
WARNING: exit code 1 from a shell command.
