gateway_mfr can't run in a mipsel platform

[idl-polun]

hi,
Sorry to bring this issue again (#7)
my platform is [ramips_24kec] (MT7628 is its soc, sorry to confuse you before)
the error as #7, it just cannot run but gateway-rs can.

and problem solved after I add static link flag in .cargo/config as below
[target.mipsel-unknown-linux-musl]
rustflags = ["-C", "target-feature=+crt-static"]

sorry I am newbie of rust, not sure if correct solution for this.
