[PULL 5/5] linux-user: Remove obsolete F_SHLCK and F_EXLCK translation

[Laurent Vivier]

From: Michael Forney <mforney@mforney.org>

These lock types are unsupported by Linux since v2.2[0][1] and
always return EINVAL (except on SPARC up until v2.6, which just
warned).

musl libc does not define these constants, so just remove them from
the translation cases.

Probably the same cause, in a different file.

This should fix the problem.

I checked on CentOS7 and this part isn't compiled because
TARGET_NR_socketcall is not defined, but I only build the
x86_64-linux-user target there.

I could reproduce building qemu-ppc64 (--target-list=ppc64-linux-user).

Hi; this fails to compile on the ppc64 box; looks like the usual
"its system includes happen to be a bit elderly" reason:
../../linux-user/syscall.c: In function ‘do_setsockopt’:
../../linux-user/syscall.c:2276:14: error: ‘IPV6_ADDR_PREFERENCES’
undeclared (first use in this function)
         case IPV6_ADDR_PREFERENCES:
              ^
../../linux-user/syscall.c:2276:14: note: each undeclared identifier
is reported only once for each function it appears in
../../linux-user/syscall.c: In function ‘do_getsockopt’:
../../linux-user/syscall.c:2931:14: error: ‘IPV6_ADDR_PREFERENCES’
undeclared (first use in this function)
         case IPV6_ADDR_PREFERENCES:
              ^

(Maybe we should think about some mechanism for getting constant
values from a local copy of the kernel headers by extending
the linux-headers scheme? It would let us cut down on the
ifdeffery...)
