[PATCH] deb-pkg: generate correct build dependencies

[PATCH] deb-pkg: generate correct build dependencies

[Masahiro Yamada]

From: Riku Voipio <riku.voipio@linaro.org>

bison/flex is now needed always for building for kconfig. Some build
dependencies depend on kernel configuration, enable them as needed:

- libelf-dev when UNWINDER_ORC is set
- libssl-dev for SYSTEM_TRUSTED_KEYRING

Since the libssl-dev is needed for extract_cert binary, denote with
:native to install the libssl-dev for the build machines architecture,
rather than for the architecture of the kernel being built.

[masahiro.yamada: add change 'flex' to 'flex | flex:native' ]

Hi Riku,

I did not get your update, but anyway I changed
'flex' to 'flex | flex:native'.

With this change, now I am able to cross-compile deb-pkg.

Applied to linux-kbuild.
