The NetBSD build system requires a shell that supports modern POSIX
features, as well as the "local" keyword in functions (which is a
widely-implemented but non-standardised feature).
Please re-run this script under a suitable shell. For example:
/path/to/suitable/shell $0 ...
The above command will usually enable build.sh to automatically set
HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
need to explicitly set the HOST_SH environment variable, as follows:
HOST_SH=/path/to/suitable/shell
export HOST_SH
\${HOST_SH} $0 ...

install from an UNPRIVED build with proper file permissions.

# TOOLDIR: TOOLDIR may be affected by settings in /etc/mk.conf, so we
# would like to use getmakevar to get the value of TOOLDIR; but we can't
# use getmakevar before we have an up to date version of nbmake; we
# might already have an up to date version of nbmake in TOOLDIR, but we
# don't yet know where TOOLDIR is.
#
# The default value of TOOLDIR also depends on the location of the top
# level object directory, so $(getmakevar TOOLDIR) invoked before or
# after making the top level object directory may produce different
# results.
#
# Strictly speaking, we should do the following:
#
# 1. build a new version of nbmake in a temporary directory;
# 2. use the temporary nbmake to create the top level obj directory;
# 3. use $(getmakevar TOOLDIR) with the temporary nbmake to
# get the corect value of TOOLDIR;
# 4. move the temporary nbmake to ${TOOLDIR}/bin/nbmake.
#
# However, people don't like building nbmake unnecessarily if their
# TOOLDIR has not changed since an earlier build. We try to avoid
# rebuilding a temporary version of nbmake by taking some shortcuts to
# guess a value for TOOLDIR, looking for an existing version of nbmake
# in that TOOLDIR, and checking whether that nbmake is newer than the
# sources used to build it.

# Run rump build&link tests.
#
# To make this feasible for running without having to install includes and
# libraries into destdir (i.e. quick), we only run ld. This is possible
# since the rump kernel is a closed namespace apart from calls to rumpuser.
# Therefore, if ld complains only about rumpuser symbols, rump kernel
# linking was successful.
#
# We test that rump links with a number of component configurations.
# These attempt to mimic what is encountered in the full build.
# See list below. The list should probably be either autogenerated
# or managed elsewhere; keep it here until a better idea arises.
#
# Above all, note that THIS IS NOT A SUBSTITUTE FOR A FULL BUILD.
