When regenerating system call tables, cope with a local kernel tree where
the kernel has been built into a separate directory (with `make O=...`) rather
than inline.
So:
- LINUX makefile var / -linux command line option give location of source tree
- LINUXBLD makefile var / -linuxbld command line option gives location of
built kernel
Syscall numbers for different architectures are now pulled in
from kernel headers. This solves 2 problems:
- we don't need to hardcode numbers for new syscalls (that don't present in typical distro headers)
- we have correct number for different archs (previously hardcoded numbers were for x86_64)
This also makes syscall numbers available for Go code, which can be useful.
Remove master process entirely, it is not useful in its current form.
We first need to understand what we want from it, and them re-implement it.
Prefix all binaries with syz- to avoid name clashes.
