Yea i had to patch gcc just to get it to compile whic= h due to various issues i have only gotten to run on the target musl system= when i use the musl wrapper to compile gcc.

how w= ould i go about fixing this linker issue? is it with binutils, gcc, or musl= ?

I greatly appreciate all the help given, I would= still be banging my head on the desk if it wasn't for your help.

Okay, that makes more sense. Note that your 'dynamic-linker' is sti= ll set to glibc's, but you are linking to /lib/libc.so (the last -L opt= ion), which is the correct musl libc. Are you using the musl-cross gcc patc= h[0]? It will solve that for you.
