Explaination of new feature

Disable profiling when building for an uClibc target via config option or libc library detection.

Justification of new feature

uClibc no longer supports profiling using gcc -pg, so building the curernt iperf3 surce using this libc fails. Ref.: https://www.kernel.org/pub/linux/libs/uclibc/Glibc_vs_uClibc_Differences.txt (at document end).

Please submit a patch to fix this and we'll look into incorporating it.

no one submitted a patch, and we can't replicate, so closing.

It's still an issue. As a workaround, changing the Makefile to remove "-pg" from the profile LD and C flags fixes it, at the obvious expense of not actually producing a profiled binary.

Is there a way (via configure or similar) to disable the profiled build, and just have a plain binary?

I want to compile iperf in Openwrt environment. Using the uclibc-0.9.33.2, it seems it could't compiled. I have to modify the Makefile.am to delete "-pg". The embedded system resource is limited, so "-pg" couldn't add if want to be used in Openwrt.

I'm unable to try at this time but the patch seem reversed, right?
