NetStar: eeprom - fix linker error

linking eeprom with libgeneric.a is not really needed and causes following
error:
../../lib_generic/libgeneric.a(string.o): In function `strcmp':
lib_generic/string.c:152: multiple definition of `strcmp'
../../examples/standalone/libstubs.a(stubs.o):include/_exports.h:24: first defined here
Remove eeprom linker script as well and generate entry point object
(to start application by jumping on its beginning) on the fly.
Out-of-tree build tested as well.
