Sami Tolvanen 08f67ef189 ANDROID: module: cfi: ensure __cfi_check alignment ...

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.

Also discard the .eh_frame section, which LLD may emit with CFI_CLANG.
