One of the things 'make distcheck' tests it that it can run builds from a
read-only source tree.  That is, remove all write permissions from the
unpacked tarball, then perform build actions (at the same time, it is
doing a VPATH build).

This includes running 'make dist' from such a source tree.

It looks to me like you have a problem where some build rule is trying
to write to srcdir (this is a common way to write rules when distributing
generated files) This probably means you have a timestamp problem in
your distribution tarball (e.g., some distributed files are older than
their source files).

Expected behaviour on a freshly unpacked tarball is that all such
generated files are up to date, and therefore no build rules will
attempt to update them.
