Hello, I implemented support for static pie generation on i386, x86_64, and arm.
This patch adds the generation of rcrt1.o which is used by gcc when compiling with the --static-pie flag. The main difference in rcrt1.o is that it is required to perform dynamic relocations which would normally occur in ldso. The new reloc_static_pie function handles parsing the elf headers, locating the dynamic section, and performing the relocations.
I'm super excited to see this! Was just thinking about asking the mailing about static pie. Looking at the code I wonder if the depends line should look something like this.
depends on DOPIC && (TARGET_arm || TARGET_i386 || TARGET_x86_64)
So that only those arches can select it.

That's actually a really good idea, I completely forgot to limit the selection to supported architectures. I'll test that change right away!
