Request #75722 Convert valgrind detection to configure option

Description:
------------
The configure script (acinclude.m4) currently searches for valgrind header file and enables valgrin support if found.

When cross-compiling the searched paths are invalid for the target platform because they below to the host system. There seems to be no way to give the build system a dedicated path where to look.

This leads to the issue, that when cross-compiling eg. for ARMv5 platform, that valgrind header file is detected - because host system is amd64 - and support is enabled but target platform will never support valgrind (valgrind requires e.g. at least ARMv7).

So the proposal is to fix/rework the detection, or better add a configuration option for this, e.g. --without-valgrind-support or --with-valgrind-support=<dir> as used for other libraries should be enough.
