-core	IAR section names for .data sections were inconsistent	
+xdc.runtime	After we split gnu.targets and gnu.targets.arm, the file
+		gnu/targets/std.h is not included when building for Arm with
+		the GCC compiler. However, there was a statement in SysMin.xdt
+		that looked up a symbol defined in that file to detect an Arm
+		GCC target together with another symbol that detects a bare
+		metal target. Only when both symbols are present an output call
+		was directed to _write() instead of fwrite().
+		When fwrite() is included for a bare metal target, a memory
+		allocation error is triggered because the initialization for 
+		standard streams requires 700 bytes of memory, while in some
+		tests for SYS/BIOS only 100 bytes of heap is available.
