use $(TEST_FILE) instead of $(2).c and other

The following script was applied:

    set -xue

    find src/ plugins/ -name '*.mk' -type f > mks

    # special cases for test file:
    # ls -d src/*-test* | sed 's@-test.*@@' | sort | uniq --repeated
    sed 's@$(2).c@$(PWD)/src/$(PKG)-test.c@g' -i \
        src/{boost,freeimage,hdf5,lapack,sdl,sdl_image,sdl_sound}.mk
    sed 's@$(2).f@$(PWD)/src/$(PKG)-test.f@g' -i src/lapack.mk

    # check
