V4L2_CID_USER_IMX_BASE value differs in v4.14 and v4.19 LTS kernels

Building strace v4.24 against 4.19 kernel headers results in following
build failure
| arm-vaisala-linux-gnueabi-ranlib libstrace.a
| In file included from ../strace-4.24/static_assert.h:31,
| from ../strace-4.24/xlat/v4l2_pix_fmts.h:4,
| from ../strace-4.24/v4l2.c:78:
| ../strace-4.24/xlat/v4l2_control_id_bases.h:36:1: error: static assertion failed: "V4L2_CID_USER_IMX_BASE != (V4L2_CID_BASE + 0x1090)"
This Linux kernel ABI breakage that occurred wrt V4L2_CID_USER_IMX_BASE
has been observed and addressed in strace upstream commit
b89a69dec2
Bump strace to version 4.25 which also addresses ABI breakage so that
strace once again builds against both v4.14 and v4.19 LTS kernel headers

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
