A common pattern for ptest is to install a Makefile that provides a make check
target. These generated Makefiles are normally full of build host paths, to
hosttools, and to files and scripts within the source or build tree. They also
commonly include the CFLAGS and CPPFLAGS. None of these build host paths
can possibly work on-target, so stripping them has no effect on the success of
the resulting ptests.
Stripping the HOSTTOOLS_DIR has this effect, for instance:
-MKDIR_P = /home/douglas/workspace/upstream/build/tmp/hosttools/mkdir -p
+MKDIR_P = mkdir -p
The curious WORKDIR/*= pattern avoids non-parseable -fdebug-prefix-map patterns
in the CFLAGS by adding an arbitrary ".", eg:
-fdebug-prefix-map=.=/usr/src/debug/rsyslog/8.37.0-r0
In all other cases, we simply remove the WORKDIR, eg:
CPP = arm-tait-linux-gnueabi-gcc -E --sysroot=recipe-sysroot ...

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.
