[Axiom-developer] rule for making NRLIBs

[Waldek Hebisch]

The current rule in src/algebra/Makefile.pamphlet does not work
during re-make. Namely, SPAD compiler fails when NRLIB directory
already exists. I propose to add the following:

--- pp/build-improvements/src/algebra/Makefile.pamphlet 2006-09-29 
21:09:42.000000000 +0200
+++ build-improvements.nn5/src/algebra/Makefile.pamphlet        2006-10-07

        @ echo compiling $*.spad to $*.NRLIB
+       rm -rf ${MID}/$*.NRLIB
        @ (cd ${MID} ; \
           if [ -z "${NOISE}" ] ; then \
            echo ")co $*.spad" | ${INTERPSYS}  ; \

One could also modify SPAD compiler to remove existing NRLIB, but
remove NRLIB from the makefile has advantage that build will fail
if NRLIB can not be recompiled -- currently build goes on using
stale NRLIB, which is very confusing for testing.
