[Buildroot] [PATCH 1/4] package/qemu: disable libssh for the host variant

[Romain Naour]

There is no host-libssh in Buildroot, avoid qemu build system
to find libssh from the host.

Under certain circumstances (host distribution, openssl version), the
qemu-system binary fail to start:

host/bin/qemu-system-aarch64: symbol lookup error: /lib64/libssh.so.4: undefined symbol: EVP_KDF_ctrl, version OPENSSL_1_1_1b

$ ldd output/host/bin/qemu-system-aarch64
	[...]
	libssh.so.4 => /lib64/libssh.so.4

Explicitely disable libssh for the host variant.

[Buildroot] [PATCH 2/4] package/qemu: disable vnc optional support for the host variant

[Romain Naour]

The vnc support is enabled by default and the build system
will try to detect automatically some external libraries
installed on the host for vnc-png, vnc-jpeg and vnc-sasl.

$ ldd output/host/bin/qemu-system-aarch64
	[...]
	libpng16.so.16 => /lib64/libpng16.so.16
or
	libpng16.so.16 => output/host/lib/libpng16.so.16
if host-libpng is built before host-qemu.

Disable explicitely thoses options to improve the build
reproducibility.

[Buildroot] [PATCH 3/4] package/qemu: disable bzip2 for the host variant

[Romain Naour]

bzip2 support is needed for reading bzip2-compressed dmg images.

But the host-bzip2 is missing from host qemu package dependency,
so the qemu build system will try to detect automatically the
external libbzip2 libraries installed on the host.

$ ldd output/host/bin/qemu-system-aarch64
	[...]
	libbz2.so.1 => /lib64/libbz2.so.1
or
	libbz2.so.1.0 => output/host/lib/libbz2.so.1.0
if host-bzip2 is built before host-qemu.

Disable explicitely bzip2 options to improve the build
reproducibility.

[Buildroot] [PATCH 4/4] package/qemu: disable SDL2 for the host variant

[Romain Naour]

There is no host variant for SDL2 library in Buildroot.
So the qemu build system will try to detect automatically the
external SDL2 libraries installed on the host.

$ ldd output/host/bin/qemu-system-aarch64
	[...]
	libSDL2-2.0.so.0 => /lib64/libSDL2-2.0.so.0

Disable explicitely sdl2 options (named sdl) to improve the
build reproducibility.
