Now that we have added gcc 5.1, it's time to make gcc 4.9 the default
version used in Buildroot.

 I think we should again update our autobuilder toolchains in this case, to make
sure we actually test the thing that we set as default.

[I have bad internet connection now so I didn't check if perhaps the autobuilder
toolchains have already been updated. If so, sorry for the noise.]

 Regards,
 Arnout

[Buildroot] [git commit] gcc: switch to gcc 4.9 as the default version

Dear Arnout Vandecappelle,

We have a few internal toolchain configurations in the autobuilders:

  http://autobuild.buildroot.org/toolchains/configs/br-arc-full-internal.config
  http://autobuild.buildroot.org/toolchains/configs/br-arm-internal-full.config
  http://autobuild.buildroot.org/toolchains/configs/br-microblazeel-full-internal.config
  http://autobuild.buildroot.org/toolchains/configs/br-powerpc-internal-full.config
  http://autobuild.buildroot.org/toolchains/configs/br-xtensa-full-internal.config

These are always using the default gcc version. However, it is true
that all the other Buildroot toolchain configuration use pre-built
external toolchains, that are stuck to whatever was the default back
when 2015.05, except the following toolchains that already use gcc 4.9:

br-aarch64-glibc.config:BR2_GCC_VERSION_4_9_X=y
br-arm-cortex-a9-glibc.config:BR2_GCC_VERSION_4_9_X=y
br-arm-cortex-a9-musl.config:BR2_GCC_VERSION_4_9_X=y

But I can certainly trigger a rebuild of the toolchains with the most
recent Buildroot, using gcc 4.9 as the default, and having one
toolchain using gcc 5.1 to catch issues. Should I do this?

Thanks,

Thomas

I think it would be interesting to do so, yes.

Thanks!
