+# There is no default TARGET; you must select one here or on the make
+# command line. Some examples:
+
+# TARGET = i486-linux-musl
+TARGET = x86_64-linux-musl
+# TARGET = arm-linux-musleabi
+# TARGET = arm-linux-musleabihf
+# TARGET = sh2eb-linux-muslfdpic
+# ...
+
+# By default, cross compilers are installed to ./output under the top-level
+# musl-cross-make directory and can later be moved wherever you want them.
+# To install directly to a specific location, set it here. Multiple targets
+# can safely be installed in the same location. Some examples:
+
+# OUTPUT = /opt/cross
+# OUTPUT = /usr/local
+OUTPUT = "@@PWD@@/prefix"
+
+# By default, latest supported release versions of musl and the toolchain
+# components are used. You can override those here, but the version selected
+# must be supported (under hashes/ and patches/) to work. For musl, you
+# can use "git-refname" (e.g. git-master) instead of a release. Setting a
+# blank version for gmp, mpc, mpfr and isl will suppress download and
+# in-tree build of these libraries and instead depend on pre-installed
+# libraries when available (isl is optional and not set by default).
+# Setting a blank version for linux will suppress installation of kernel
+# headers, which are not needed unless compiling programs that use them.

+# Something like the following can be used to produce a static-linked
+# toolchain that's deployable to any system with matching arch, using
+# an existing musl-targeted cross compiler. This only works if the
