#230275 — Cannot compile qemu

I tried to compile qemu by myself (this is not the first time).
I issued
%sudo apt-get build-dep qemu
%apt-get source qemu
and then
in qemu directory
%debuild -us -uc -b

Hi,
I compiled qemu debian packages customized (basically removing all the stuff
and architectures I do not need) few weeks ago.
I used qemu (svn/git) source and debian packaging for buster.
To compile the default setup you need a lot of cross-compile tools. 
My goal was to get the arm emulator without GUI. It took me about a week to
get the proper configuration (altering the debian defaults).
Either you install all the tools, or you need to adjust the configuration.

I just wonder why you compile config-temp/qemu-conf.exe <<<<< EXE?
I admit this is very odd

regards

No idea whether this leads somewhere, but FWIW, sys/endian.h is in
libbsd-dev:

| tomas@trotzki:~$ apt-file search sys/endian.h
| freebsd-glue: /usr/include/freebsd/sys/endian.h
| libbsd-dev: /usr/include/bsd/sys/endian.h

Perhaps there's a buglet in quemu's build deps, perhaps there are
other forces at play.

Cheers
