     But it isn't installed and, BTW, the installed binutils executables 
aren't prefixed with x86_64-linux-musl-

     When I remove the line 'OUTPUT = /usr/pkg'  in config.mak, to leave 
it use the default, then the installation occurs in subdir 'output' of 
the source tree, and it seems much more familiar to me, with more 
subdirs, such as libexec, share and x86_64-linux-musl, which are not 
present otherwise. And all the executables are correctly prefixed.

     Therefore the problem is restricted to the processing of the custom 
install dir. Given the cross-compiler is sysrooted, this isn't a big 
deal, but better to know.
