odd meson failure: Unknown variable "exe_name"

odd meson failure: Unknown variable "exe_name"

[Peter Maydell]

On my x86-64 Linux box, one of my local build trees turned out not
to work:

$ rm -rf build/x86 && mkdir build/x86 && (cd build/x86 &&
'../../configure'
'--target-list=arm-softmmu,aarch64-softmmu,arm-linux-user,aarch64-linux-user'
'--enable-debug' '--cc=ccache gcc' '--audio-drv-list=pa'
'--with-pkgversion=pm215' '--enable-trace-backends=log,dtrace'
'--enable-docs')

fails with
[...]
Program keycodemapdb/tools/keymap-gen found: YES
Program scripts/decodetree.py found: YES
Program ../scripts/modules/module_block.py found: YES
Program nm found: YES
Program scripts/undefsym.sh found: YES
Program scripts/feature_to_c.sh found: YES

../../meson.build:1030:14: ERROR: Unknown variable "exe_name".

A full log can be found at
/home/petmay01/linaro/qemu-from-laptop/qemu/build/x86/meson-logs/meson-log.txt

ERROR: meson setup failed


This is the same box that's worked fine for merge testing, so
presumably something about the particular set of configure
options is tripping it up.

thanks

Dropping the '--enable-trace-backends=...' option lets it pass,
so that's the area where the problem is.

It's a rebase issue from the introduction of fuzzing binaries. I will send
a fix.
