If I get this correctly, 'posix/vfork.c' is pulling the arch dependent 'sysdeps/unix/sysv/linux/riscv/vfork.S', which then feeds this to the assembler. vfork.S has a '#include <linux/sched.h>' directive. Per commit https://github.com/torvalds/linux/commit/7f192e3cd316ba58c88dfa26796cf77789dd9872, there is a new struct defined to support clone3() in linux v5.3. Since struct definitions are not proper assembler directives, I believe this is the source of the problem.
Should be fixed in sys-libs/glibc-2.29-r6 with https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c8f2c70c47446347c9a9e382c4015be3736e4dc3 It pull in upstream fix into 2.29 and 2.30 gentoo glibc branches.
