Change 'microblaze_asm_output_ident' so that instead of just switching
section to .sdata2/.rodata it uses the assembler .pushsection and
.popsection directives to preserve the section context when emitting the
ident string content.
This resolves issues associated with the use of the .sdata2/.rodata
operation in cases where emitted assembly after the ident output is
incorrectly in the .sdata2/.rodata section instead of .text or any other
expected section. This results in assembly failures including operations
with symbols across different segments.
