[Buildroot] [PATCH v2 1/2] rt-tests: disable for uclibc mips

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

Ryan, Peter, All,

On 2014-02-23 00:07 +0100, Ryan Barnett spake thusly:
> rt-tests is not supported by a uclibc toolchain that does not implement
> _pid in struct sigevent. Currently this is all MIPS architectures
> in uclibc.

Gah! This is not correct Kconfig syntax and breaks:

    $ make menuconfig
    [...]
    package/rt-tests/Config.in:10: syntax error
    package/rt-tests/Config.in:9: invalid option
    package/rt-tests/Config.in:36: syntax error
    package/rt-tests/Config.in:35: invalid option
    make[1]: *** [oldconfig] Error 1

Peter, can we revert this change until we have a proper fix, please?

Ryan, what were you trying to do here? Why can you use something like
(variable abbreviated for clarity):

    depends on ! ( UCLIBC && ( mips || mipsel || mips64 || mips64el ) )

Ditto.
