That's the right fix.  The rationale for this pattern is that
aclocal.m4 is a generated file, created by the aclocal binary, which
contains all of the macros used by rxvt from /usr/share/aclocal (i.e.
the X macros).  Thus, it will be destroyed at configure time.
acinclude.m4 is for local macros and is a source file.

Typically you see this pattern in packages which ship a non-pristine
aclocal.m4, so when we re-generate it macros are lost.  That normally
means that the package won't build though.
