Saul Wold 97586f5d62 recipetool: Fix circular reference in SRC_URI
When creating a new recipe.bb file for a binary, don't use BP which
includes the version information, instead use BPN which is just the
name base Package Name.

Since PB is not specified, it takes the default:
PV = "1.0+git${SRCPV}"

But SRCPV is defined in terms of the SRC_URI, which leads to infinite
recursion (traceback below). Here are the pertinent variables which
cause the recursion:

SRC_URI = "git://github.com/lvc/abi-dumper;protocol=https;subdir=${BP}"
BP = "${BPN}-${PV}"
PV = "1.0+git${SRCPV}"
SRCPV = "${@bb.fetch2.get_srcrev(d)}"

def get_srcrev(d, method_name='sortable_revision'):
    # ... trimmed
    scms = []
    fetcher = Fetch(d.getVar('SRC_URI').split(), d)
    # ... trimmed

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.
