GCC 11.1.10 ld: warning: .init_array section has zero size

[Chris Packham]

Hi,

I'm trying to migrate our builds to GCC 11.1.0 + binutils 2.36.1 and I'm 
getting a weird linker warning for ARM (I'm also building for MIPS64 
where I don't see the warning).

$ rm -f test; make CC=arm-unknown-linux-gnueabi-gcc test
arm-unknown-linux-gnueabi-gcc     test.c   -o test
/usr/bin/../lib/gcc/arm-unknown-linux-gnueabi/11.1.0/../../../../arm-unknown-linux-gnueabi/bin/ld: 
warning: .init_array section has zero size
/usr/bin/../lib/gcc/arm-unknown-linux-gnueabi/11.1.0/../../../../arm-unknown-linux-gnueabi/bin/ld: 
warning: .fini_array section has zero size

I'm not sure if this is a GCC or a binutils problem so I figured I'd 
start with binutils since the warning is coming from ld. I'm not sure 
it's causing any specific problem but it might be upsetting some 
autoconf checks (one package I'm having problems with is failing to 
detect some functions with AC_CHECK_FUNCS).

Is there any flag that I can pass to get rid of this warning?

Thanks,
Chris
