build: use full paths on compile/link targets

This makes the compile commands clearer when building in parallel (with `make -j`) and ensures that `__FILE__` includes the full build-time path (relative to the root of the repository) whenever it is referenced, such as in failed assert() messages (currently the full path is only shown in errExit() messages). Example: Before: firejail: main.c:100: main: Assertion `1 == 2' failed. Error src/firecfg/main.c:100: main: malloc: Cannot allocate memory After: firejail: ../../src/firejail/main.c:100: main: Assertion `1 == 2' failed. Error ../../src/firecfg/main.c:100: main: malloc: Cannot allocate memory Commands used to search and replace: $ git grep -Ilz '^MOD_DIR =' -- '*Makefile' | xargs -0 -I '{}' \ sh -c "printf '%s\n' \"\$(sed -E \ -e 's|^MOD_DIR = src/(.*)|MOD = \\1\\nMOD_DIR = \$(ROOT)/src/\$(MOD)|' \ -e 's:^(PROG|SO) = [^.]+(\.so)?$:\\1 = \$(MOD_DIR)/\$(MOD)\2:' \ '{}')\" >'{}'" $ git grep -Ilz '^HDRS :=' -- '*.mk' | xargs -0 -I '{}' \ sh -c "printf '%s\n' \"\$(sed -E \ -e 's|wildcard (\*\..)|wildcard \$(MOD_DIR)/\\1|' '{}')\" >'{}'" Note: config.mk.in, src/fnettrace/Makefile and src/include/common.h were edited manually. This is a follow-up to netblue30#5871.
