i think you need . in PATH for this to work

i think you can pass 'CROSS_COMPILE=' to configure
and then you don't need such symlinks.

no, the right way is to run make install
(DESTDIR and --prefix works the usual way)

there are only a small number of files that are copied
this way, if you directly use the build directory then
the target specific header files are not set up correctly,
i think you can hack that around with a bits symlink and
appropriate modifications to musl-gcc and the specs file,
but such hacks are not guaranteed to work in the future.
