[PATCH] perf: Don't hardcode host include path for libslang

[Florian Fainelli]

Hardcoding /usr/include/slang is fundamentally incompatible with cross
compilation and will lead to the inability for a cross-compiled
environment to properly detect whether slang is available or not.

If /usr/include/slang is necessary that is a distribution specific
knowledge that could be solved with either a standard pkg-config .pc
file (which slang has) or simply overriding CFLAGS accordingly, but the
default perf Makefile should be clean of all of that.
