Why don't you use the configure script? It is not autotools-based, but
the official build instructions suggest to use it:

    $ ./configure
    $ make
    $ sudo make install

The configure script allows to explicit disable unused feature, using
--without-<foo> options.

Could you have a look at this?

Also, the manual says that on ARM, only ARM >= v6 is supported. So this
probably means that:

config BR2_PACKAGE_UFTRACE_ARCH_SUPPORTS
        bool
        default y if BR2_arm

should instead be:

	default y if BR2_ARM_CPU_ARMV6 || BR2_ARM_CPU_ARMV7A

Thanks a lot!
