Module Name:src

Removed Files:

Log Message:
ld.elf_so powerpc: remove bogus ldscript
This ldscript is not needed and actually makes things worse by putting
everything in one LOAD section, which then needs to have rwx permission.
Remove it so that we get two LOAD sections with better permissions.
Fixes PR 57323.
