[Buildroot] [PATCH 4/4] toolchain-external: add OSELAS 2014.12.0 Cortex-M3 toolchain

[Yann E. MORIN <yann.morin.1998@free.fr>]

Guido, All,

On 2015-06-26 14:33 -0300, Guido Mart?nez spake thusly:
> Binary toolchain based on uClibc for Cortex-M3 processor based on GCC
> 4.9.2.
> 
> This toolchain has no resolver support, thus, we don't select
> BR2_HAS_RESOLVER_SUPPORT.

We prefer sha256 when locally computed.

But in this case, we do have an upstream-provided set of hashes:

    http://debian.pengutronix.de/debian/dists/sid/main/binary-i386/Packages

so we should use it (even though it is not https... :-( ):

    # From: http://debian.pengutronix.de/debian/dists/sid/main/binary-i386/Packages
    sha1    75e7ae45b514b10ad64ff5588770434cea755496  oselas.......
    sha256  1c542d3aad4e592270918d54bb02a90580902d573dc4d9b59aabfd0697220f3e  oselas.......

Otherwise, looks good.

Yet, there is also a 64-bit variant for this toolchain, so maybe we
could download the one corresponding to the user's host, like so:

    [...]
    else ifeq ($(BR2_TOOLCHAIN_EXTERNAL_OSELAS_ARM_CORTEX_M3_201412),y)
    TOOLCHAIN_EXTERNAL_SITE = http://debian.pengutronix.de/debian/pool/main/o/oselas.toolchain/
    ifeq ($(HOSTARCH),x86)
    TOOLCHAIN_EXTERNAL_SOURCE = oselas.toolchain-[...]_i386.deb
    else
    TOOLCHAIN_EXTERNAL_SOURCE = oselas.toolchain-[...]_amd64.deb
    endif
    else ifeq (...)
    [...]

And of course, no longer needed to have the option select
BR2_HOSTARCH_NEEDS_IA32_LIBS in the Config.in, since there would be a
64-bit-native variant.

(But don't forget to add the hashes for that variant, too! ;-) )

Regards,
Yann E. MORIN.
