John. I am not using the makefile method. I try on going away frome qnx recursive make method. Essentially. I just want to use GCC and binutils and nothing more to build more open source software packages

Since, I do not rebuild qnx compiler, and only use the downloaded toolchain along with native/target libraries provided by this project, I do not have control for the linking process.

That path was preconfigured while building the compiler for qnx. it was probably defined using the preprocessor while building GCC:

I tried telling the linker where to find the c-runtime using -L -I search path arguments and the linker still error out, saying that path to object armv7/armle-v7/lib/crt1* not found. Certainly, since I am making a build environment, i do not want to be in the target directory where the linker can find its C-runtime library all the time.
