[Buildroot] [PATCH] package/linux-tools: Disable libtracevent detection

[Buildroot] [PATCH] package/linux-tools: Disable libtracevent detection

[Florian Fainelli]

Since upstream Linux commit 6898e60f709b0047206110d3ec9f4612210e3ff7
("perf build: If libtraceevent isn't present error the build") present
in Linux 6.4 and newer, Linux will fail to build if libtraceevent is not
present. Since we do not currently have support for libtracevent in
buildroot, pass NO_LIBTRACEVENT=1 to get perf to build again.
