ld: Issue an error for GC on __patchable_function_entries section
__patchable_function_entries section is generated by a compiler with
-fpatchable-function-entry=XX. The assembly code looks like this:
---
.text
.globl _start
.type _start, %function
_start:
.section __patchable_function_entries,"aw",%progbits
.dc.a .LPFE1
.text
.LPFE1:
.byte 0
---
But --gc-sections will silently remove __patchable_function_entries
section and generate corrupt result. This patch disallows garbage
collection on __patchable_function_entries section without linked-to
section.
