-static just fixes the issue caused by --nmagic. If -Wl,--nmagic + -static do not help, I would suggest you write a linker script for your needs.

which is 64K for my toolchain.

This is because --nmagic disable linking against shared libraries (but not
mentioned in the ld manual). GCC doesn't know that and still passes -lgcc_s
to ld. But libgcc_s.a cannot be found. Adding -static when linking should
work for you.
