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. Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
