Merge the following new data sections generated by current
LLVM versions:

  .bss..L* .bss..compoundliteral*
  .data..L* .data..compoundliteral*
  .rodata..L* .rodata..compoundliteral*

Also drop the unnecessary rules to merge .rela sections.

bf3b3bbdfc ANDROID: kbuild: ensure __cfi_check is correctly aligned 
On modules with no executable code, LLVM generates a __cfi_check stub,
but won't align it to page size as expected. This change ensures the
function is at the beginning of the .text section and correctly aligned
for the CFI shadow.
