43549bdaf4 Exclude -flto when building *genassym.o
The build process generates *assym.h using nm from *genassym.o (which is
in turn created from *genassym.c).

When compiling with link-time optimization (LTO) using -flto, .o files
are LLVM bitcode, not ELF objects. This is not usable by genassym.sh,
so remove -flto from those ${CC} invocations.

db2e4d79bb Implement linux version of ptrace(2). It's nowhere near complete,
but it allows to use 64 bit linux strace(1) on 64 bit linux binaries.

f971c436f5 pass -fPIC to the assembler, not linker
-fPIC has no effect on linking although it seems to be ignored by
GNU ld.bfd.  However, it causes ld.lld to terminate with an invalid
argument error.

3e47d7787e Remove unneeded includes of opt_kdtrace.h.
As of r258541, KDTRACE_HOOKS is defined in opt_global.h, so opt_kdtrace.h
is not needed when defining SDT(9) probes.

5f069937a3 Implement epoll family system calls. This is a tiny wrapper
around kqueue() to implement epoll subset of functionality.
The kqueue user data are 32bit on i386 which is not enough for
epoll user data, so we keep user data in the proc emuldata.

Initial patch developed by rdivacky@ in 2007, then extended
by Yuri Victorovich @ r255672 and finished by me
in collaboration with mjg@ and jillies@.
