If this is building C++ code, then the problem is likely in the linker.
Try this:

This reduces the stub pressure by about 50%.  I also installed this
yesterday to fix a related problem:

	* pa.c (pa_output_function_prologue, pa_output_function_epilogue): Move
	updating of total_code_bytes from prologue to epilogue.

The updating of total_code_bytes in the prologue changed caused the call
sizes to change in a function that spanned the 240000 byte boundary.  This
caused the branch distance of any branch over a call to increase, and
sometimes exceed the range of the branch.
