[Buildroot] [PATCH 2/3] uclibc: add explicit setup of ARC-specific options

[Yann E. MORIN]

Alexey, All,

On 2014-10-30 16:57 +0300, Alexey Brodkin spake thusly:
> As with other architectures for ARC we need to have an ability to set
> specific options in uClibc.
> 
> In particular this is required for selection of ARC ISA version.

I know you just followed the existing style of the options around, but
since this option is a "string", the default values must be enclosed
between double quotes, like:

    default "ARC_CPU_700" if BR2_arc750d

The fact that it works is that we are lucky there are no symbol named
ARC_CPU_700, otherwise its value would be used, not the string
"ARC_CPU_700".

I would prefer we get proper kconfig code, even though the rest of the
code around is not correct. Maybe a preliminary patch to fix that? ;-)

Otherwise, looks good to me.

Regards,
Yann E. MORIN.
