The gmu package cannot be compiled

[FantasyGmm]

Describe the bug

Because CC is set to CC=/opt/FunKey-sdk/bin/arm-funkey-linux-musleabihf-gcc in gmu's funkey.mk, when compiling as a package for buildroot, the compiler cannot be found because sdk does not exist at all

To Reproduce
Just need clone this repo,then make fun

Expected behavior
This is my direct attempt to compile the system image, as I did not compile the SDK, so he cannot find the compiler and library he needs in the opt directory

Yeah that's a package I created from some sources I got recently but it's badly designed (requires a ./configure which will get your env compilation flags)... So I would need to modify it, not sure when though. For now, just place the toolchain in /opt/FunKey-sdk/ and that will do the job.

I tried to put SDK under/opt, it can compile but failed during installation
