+Subject: [PATCH] find-debuginfo.sh: Remove non-allocated NOBITS sections from
+ minisymtab.
+
+In the minisymtab section (the .gnu_debugdata embedded ELF image) we
+do not need unallocated sections (except for the SYMTAB and STRTAB
+sections we are creating). We already remove PROGBITS and NOTES. Also
+remove NOBITS sections. They should not really take up much (any) space
+but they still add to the section tables. These sections might be created
+with the new --keep-section support (which puts the actual section in
+the main ELF binary, and a NOBITS variant in the .debug file).
+
+Also binutils objcopy seems to sometimes add them anyway filled with
+zeros instead of marking them NOBITS.
+
