GCC unable to find C standard headers

[marchingband]

Hi thanks so much for this.
I was able to build the toolchain, but my builds fail with fatal error: stdlib.h: No such file or directory
Do you happen to know a solution for this?
Perhaps it could be a useful addition to the instructions, if this is something encountered by other users.
Thanks again, very excited to use this toolchain on my new mac.
