Details:

The following makefile illustrates what I regard as a bug in make's library
search mechanism. In short .LIBPATTERNS does not work as either a pattern or
target dependent variable.

all: dynamic.show static.show

dynamic.%: .LIBPATTERNS = lib%.so lib%.a
static.%:  .LIBPATTERNS = lib%.a lib%.so 

libs := -lm -lnsl

dynamic.show: $(libs)
static.show:  $(libs)

%.show:
        @ echo "LIBPATTERNS and VPATH resolution: $(.LIBPATTERNS) : $@ : $^"
