This is useful if you want to use absolute paths to the compiler and linker rather than depend on paths. I have made a number of changes and I have not tested rtems-ld. Are you able to run some tests on rtems-ld for me ? I tried rtems-ld to compile python.rap for arm realview_pbx_qemu_a9 bsp using such options: '-B arm/realview_pbx_qemu_a9 -r /opt/rtems-4.11' and rtems-ld can link the final rap image. At last when load the python.rap, the simpile xx.py file can be correctly executed. Yeah, I do some debug, and found that use '-B' can let gcc search the correct libs. I found that '-B' and '-r' should be set both, otherwise rtems-ld will complains errors 'No RTEMS path provide with arch/bsp'.
I have just updated the code so the -r is only needed if rtems-ld is not installed. If installed giving it a valid prefix it will set the RTEMS path (-r) to the prefix. This means if you build RTEMS and install it and built the rtl-host code and installed it the paths will default to the $prefix.
The test to determine the prefix is ok and not great but should work for standard installs. Anything else requires the -r option.
