GCC's garbage collector works for Microblaze for quite a long time but none
has enabled it.
The same change has be done for example by commit fac4790491 ("arc:
Eliminate unused code and data with GCC's garbage collector").
Before:
text data bss dec hex filename
588760 33592 39192 661544 a1828 u-boot
After:
text data bss dec hex filename
504504 32164 38608 575276 8c72c u-boot
Which saves almost 15% of memory footprint.
Also group symbols/functions to proper section.
