I notice that the patch only modifies the linker script

I remembered --gc-sections option is ignored by the linker on MinGW, so 
to enable the option also should modify libbfd?
I saw the initial patch in ld/11539 also modify bfd, but I don't know 
whether the bfd part is fixed now.



And you also added

KEEP(*(.eh_frame*))

When I tested the KEEP half one year ago, I really found 
KEEP(*(.eh_frame*)) can make all --gc-sections target to work, but exe 
target using the KEEP will increase the size. Can we only use the KEEP 
to dll target?
