Profiling on Espressif MCUs woes

[DrMickeyLauer]

I'd need a macOS and/or Linux binary though…

Samuel Obuch had an issue using it, and I traced it to a VAXism in gprof. Until that can be addressed, histogram resolution is reduced for gprof compatibility. Also having a bit of trouble with the github builder today.

OpenOCD profiling speedups for ESP32 and ESP32-S2 have been merged to mainline.

It seems the older RISCV cores do not: https://github.com/espressif/vscode-esp ... 3236319637

Hopefully it might be enabled for future RISCV cores.

OpenOCD multi-histogram encoder has been merged to mainline in time for the next OpenOCD release
