[PATCH] perf build: Fix static linking with libopencsd.

[PATCH] perf build: Fix static linking with libopencsd.

[Branislav Rankov]

Add -lstdc++ to perf when linking libopencsd as it is a dependency. It
does not hurt to add it when dynamic linking.

Filter out -static flag when building plugins as they are always built
as dynamic libraries and -static and -dynamic don't work well together
on arm and arm64.
