The asm-prototypes.h file is used to provide dummy function declarations
for genksyms, when processing asm files with EXPORT_SYMBOL. Make sure
that any architecture defines get out of our way. x86 currently has an
issue with memcpy on 64bit with CONFIG_KMEMCHECK=y and with
memset/__memset on 32bit:
$ cat init/test.c
#include <asm/asm-prototypes.h>
$ make -s init/test.o
$ make -s init/test.o

During real build, this manifests itself by genksyms segfaulting.

Do not try to recover too early and segfault when parsing invalid
declarations such as
echo 'int (int);' | scripts/genksyms/genksyms
echo 'int a, (int);' | scripts/genksyms/genksyms
echo 'extern void *__inline_memcpy((void *), (const void *), (__kernel_size_t));' | scripts/genksyms/genksyms
The last one was a real-life bug with
include/asm-generic/asm-prototypes.h on x86_64.
