You must do something fundamentally wrong.  Where does the -f come
from?

If you pass the option to avr-gcc, it must be preceded by a »-Wl,«,
this tells the compiler driver to pass the remainder verbatim to the
linker.

Alternatively, use your own linker command (avr-ld).  You can see the
defaults by running avr-gcc's link step with -v.  cut&paste this
command line, and include your own linker option then.

Note that the --section-start linker option has two leading dashes.
I'm not sure, i think when you're passing it directly on the linker
command line, you need to replace the first equal sign by a space:

avr-ld ... --section-start .mydata=0x2e00
