Fix linking MSP430 files created by gcc's LTO optimizer.
When invoking GCC with "-g -flto", the compiler will create LTO objects
with debug information. The objects created are "simple ELF" objects (see
libiberty/simple-object-elf.c) and do not have target-specific sections.
When the MSP430 linker sees one of these objects without a .MSP430.attributes
section it errors:
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses MSP430X instructions but /tmp/ccynqIwudebugobj uses unknown
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model whereas /tmp/ccynqIwudebugobj uses the unknown code model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small data model whereas /tmp/ccynqIwudebugobj uses the unknown data model
> error: /tmp/cc4LhbEI.ltrans0.ltrans.o uses the small code model but /tmp/ccynqIwudebugobj uses the unknown data model
> failed to merge target specific data of file /tmp/cc4LhbEI.ltrans0.ltrans.o
The following patch allows these debug LTO objects to be linked with other
MSP430 objects even if they do not have a .MSP430.attributes section.
bfd * elf32-msp430.c (elf32_msp430_merge_mspabi_attributes): Do not
error when .MSP430.attributes section is missing from objects
created by LTO.
