A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
postfix. So the second and later asm files #included in the same C file
(often through standard headers like ioctl.h) yields no symbols.

There's a missing semicolon after the assignment to FNAME (so the assignment
of STUBDEF on the next line doesn't see the value), and it helps to export
variables before calling a subshell.
