The reference to installdirs-local indicates it's trying to do this part
of src/Makefile:

installdirs-local:
$(MKDIR_P) '$(DESTDIR)$(pgxsdir)/$(subdir)'

You sure you didn't accidentally insert an "@" into that line?

Another possibility is that you somehow messed up the definition of
MKDIR_P in src/Makefile.global, or messed up the configure logic that
substitutes a correct value for that (though I'd have thought that such
a mistake would lead to failures earlier than here). The relevant line
in src/Makefile.global.in is

MKDIR_P = @MKDIR_P@

and this should get expanded to something like

MKDIR_P = /bin/mkdir -p

in src/Makefile.global (specific command varies depending on platform).
