My problem is that our real-time operating system (RTEMS) is somewhere in

of stuff which depends on the Newlib struct _reent since this pulls in a lot
of dependencies. The heavy weight functions are just used for the
initialization (env.c) and error reporting. Containing the heap allocation
functions helps to control the memory used by OpenMP computations.
Heap allocations are everywhere in libgomp, not just in initialization,
for parallel, offloading, tasking, worksharing constructs, ...
You won't get far without that.
I would like to use a specialized heap for OpenMP and not the general
purpose malloc(), etc.
