Patches for binutils on Minerva

0001-Add-support-for-Minerva.patch

Add support for Minerva

Teaches the assembler, BFD, and the linker about the Minerva target triple.

We set '/' to not start a comment in GAS, as the QEMU port uses it for division in constant expressions in assembly files (cf. as --divide).

/usr/lib/Loader.so is set as the default ELF interpreter.

On AArch64, we set COMMONPAGESIZE to enable RELRO support.

0002-ld-Add-Bsymbolic-non-weak-functions.patch

ld: Add -Bsymbolic-non-weak-functions

This option is a subset of -Bsymbolic-functions: only STB_GLOBAL are considered. Vague linkage functions are STB_WEAK. A vague linkage function may have different addresses in a -Bsymbolic-functions linked shared object and outside the shared object. -Bsymbolic-non-weak-functions can keep pointer equality while providing most benefits: (a) fewer JUMP_SLOT (symbol lookups) (b) avoid PLT entries for default visibility defined functions.
