Previously, the linker script forcefully kept all .lib.stub sections, unnecessarily bloating the binary. Now, the script is LTO and --gc-sections friendly.

--nmagic was also added to the linker, because page alignment is not required on the PSP. This further reduces binary size.

Accompanying changes for the psp crate are found in: overdrivenpotato/rust-psp#118

Relax mipsel-sony-psp's linker script
