At present, CONFIG_SHELL becomes /bin/sh if its bash and /bin/bash if not. This isn't deterministic and leads to changes in ptest packages which include Makefiles. At first glance you'd think we'd hardcode to /bin/sh since most system shells are sane. Sadly the dash vs. bash leads to quoting differences in configure. The bash default is probably the safest option since configure tries to find bash and this is what most systems would end up using. The end result is a more consisent build environment.

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.
