lm32: internal compiler error: in dwarf2out_frame_debug_expr, at dwarf2cfi.c:1809

[Sebastian Huber]

Hello,

I noticed an internal compiler error on lm32 while testing the new build 
system:

https://devel.rtems.org/ticket/4089

If someone is interested in the lm32 support, then this bug should be 
reported to GCC. Otherwise, this architecture should be obsoleted in 
RTEMS 6 and removed in RTEMS 7 from my point of view.
