[Buildroot] [PATCH] linux-tool-perf: permit TUI build

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

John, All,

On 2018-04-02 13:51 +0100, John Keeping spake thusly:
> Since Linux 3.10, perf's NO_NEWT configuration option simply sets
> NO_SLANG=1 and there is no dependency on libnewt.
> 
> We already handle NO_SLANG correctly based on whether or not
> BR2_PACKAGE_SLANG is selected, so all we accomplish by setting NO_NEWT=1
> is disabling perf's TUI when all of the dependencies are available.
> 
> Linux 3.10 is almost 5 years old now, so there doesn't seem to be any
> point in jumping through additional hoops to make perf from older kernel
> versions build when the newt package is not available.

But we still support kernels back to 3.0...

I would instead suggest you add an option in
package/linux-tools/Config.in:

    config BR2_PACKAGE_LINUX_TOOLS_PERF_TUI

And do a check in package/linux-tools/linux-tool-perf.mk.in whether it
is valid o not, if needed.

Regards,
Yann E. MORIN.
