----------------------------+-----------------------------------------------
PALP fails to build in parallel with GNU `make`. Some output from `make
-d` (debug):
{{{

It's not clear why this happens, but it breaks building spkgs in parallel
(#8306). As we've done with other packages, forcing a serial build helps.
PALP has a `Makefile` and a `GNUmakefile`. GNU `make` prefers the latter.
It seems that `export MAKE="make"` in `spkg-install` is not enough to
suppress a parallel build, but adding the special target
[http://www.gnu.org/software/automake/manual/make/Special-Targets.html
#index-g_t_002eNOTPARALLEL-248 .NOTPARALLEL] to `GNUmakefile` works.
Building in parallel appears to work if I replace `GNUmakefile` with
`Makefile`, but the compiler and compiler flags are different. The
package does not have an [obvious] test suite.
#7071 is another PALP ticket.
