do you have a static linked gcc with musl support on the target?
does the configure script run on the target?
you need to be more clear and provide more information like:

- can gcc compile a minimal program (empty main)?
- where does gcc/ld fail, how were they invoked (gcc -v)?
- in the executable is the loader properly set up (readelf)?
- check if the loader/libc at the right path
- can you run the executable with the loader explicitly?
- strace the executable, where does it fail?
