+* Add a configure option --enable-elf-stt-common to decide whether ELF
+ assembler should generate common symbols with the STT_COMMON type by
+ default. Default to no.
+
+* New command line option --elf-stt-common= for ELF targets to control
+ whether to generate common symbols with the STT_COMMON type.
+
* Add ability to set section flags and types via numeric values for ELF
based targets.
