- Prepend local variable names w/ a function-unique prefix to prevent collisions and leaks.

- Implemented consistent build/configure/install variable handling with per-level [0123]
  defaults. Fixes lack of uniform CFLAGS (-g3 -O0) usage. The new build variables include:
  - {AR,CC,RANLIB}_{BUILD,CONFIGURE,INSTALL},
  - {{C,LD,MAKE}FLAGS_{BUILD,CONFIGURE,INSTALL}}{,_EXTRA},
  - CONFIGURE_ARGS{,_EXTRA}, ENV_VARS_EXTRA, LIBTOOL_MIDIPIX, and PREFIX_EXTRA.
