In optimized builds, CFLAGS contains various optimizations such as -O3, and is propogated by automake to all files. To work-around this, isolate MPIR_Breakpoint() and other MPIR_* symbols into its own library built with debugger specific CFLAGS. To prevent CFLAGS from being polluted elsewhere in the make tree, build this in its own tiny stand-alone makefile. Fixes open-mpi#7757 Signed-off-by: Austen Lauria <awlauria@us.ibm.com> (cherry picked from commit 6d82003)
