tools: Fixed MIPS builds due to struct flock re-definition
Building perf for MIPS failed after 9f79b8b72339 ("uapi: simplify __ARCH_FLOCK{,64}_PAD a little") with the following error: CC /home/fainelli/work/buildroot/output/bmips/build/linux-custom/tools/perf/trace/beauty/fcntl.o In file included from ../../../../host/mipsel-buildroot-linux-gnu/sysroot/usr/include/asm/fcntl.h:77, from ../include/uapi/linux/fcntl.h:5, from trace/beauty/fcntl.c:10: ../include/uapi/asm-generic/fcntl.h:188:8: error: redefinition of 'struct flock' struct flock { ^~~~~ In file included from ../include/uapi/linux/fcntl.h:5, from trace/beauty/fcntl.c:10: ../../../../host/mipsel-buildroot-linux-gnu/sysroot/usr/include/asm/fcntl.h:63:8: note: originally defined here struct flock { ^~~~~ This is due to the local copy under tools/include/uapi/asm-generic/fcntl.h including the toolchain's kernel headers which already define 'struct flock' and define HAVE_ARCH_STRUCT_FLOCK to future inclusions make a decision as to whether re-defining 'struct flock' is appropriate or not. Make sure what do not re-define 'struct flock' when HAVE_ARCH_STRUCT_FLOCK is already defined.
