Actually, this particular machine is actually running RELENG_4_10. My
bad. So I'm posting this back to -questions. :-)

I have successfully worked around the problem by passing -DLITE to make
when building editors/vim. When I remove -DLITE, the error resurfaces.
The following binaries remain affected (there are others, but they are
irrelevant to vim):
/usr/X11R6/bin/glxinfo:
libc_r.so.4 => /usr/lib/libc_r.so.4 (0x28221000)
libc.so.4 => /usr/lib/libc.so.4 (0x2831e000)
/usr/X11R6/bin/glxgears:
libc_r.so.4 => /usr/lib/libc_r.so.4 (0x281ac000)
libc.so.4 => /usr/lib/libc.so.4 (0x28264000)
What is causing this? My first suspicion is ccache. Could it be that I
have set the following variables in /etc/make.conf?
CC=/usr/local/bin/cc
CPP=/usr/local/bin/cpp
CXX=/usr/local/bin/c++
( /usr/local/bin/c{c,pp,++} are symlinked to /usr/local/bin/ccache. )
Apart from that, the only difference between the system in question and
a stock FreeBSD installation is the following MARK_ARGS pair in
/usr/local/etc/pkgtools.conf:
'editors/vim' => '-DLITE -DWITH_CSCOPE -DWITH_PERL -DWITH_PYTHON -DWITH_RUBY -DWITH_TCL'
