can't get PIE with linker scripts

[Boshi Wang <wangboshi@xxxxxxxxxx>]

I want to compile a PIE with a linker script. But I can't get a PIE if I use a linker script even an inner linker script. Is it expected?

   ~/code/pie-test$ aarch64-linux-gnu-ld --verbose | sed -n '/OUTPUT_FORMAT/,/^}/p' > default.lds
   ~/code/pie-test$ aarch64-linux-gnu-gcc -fPIE -pie -T default.lds -o pie-lds main.c
