perf tools: Fix cross compile for ARM64
Currently when cross compiling perf tool for ARM64 on my x86 machine I get this error:
arch/arm64/util/sym-handling.c:9:10: fatal error: gelf.h: No such file or directory #include <gelf.h>
For the build, libelf is reported off:
Auto-detecting system features: ... ... libelf: [ OFF ]
Indeed, test-libelf is not built successfully:
more ./build/feature/test-libelf.make.output test-libelf.c:2:10: fatal error: libelf.h: No such file or directory #include <libelf.h> ^~~~~~~~~~ compilation terminated.
I have no such problems natively compiling on ARM64, and I did not previously have this issue for cross compiling. Fix by relocating the gelf.h include.
