Symbols defined in a linker script are assigned type STT_NOTYPE, but
the __resolve_sym() function in ldelf only supports STT_OBJECT and
STT_FUNCTION. As a result, it is impossible to resolve STT_NOTYPE
symbols at runtime. This causes an error in shared libraries when
ftrace is enabled:
# Platform: QEMU
$ make CFG_FTRACE_SUPPORT=y CFLAGS_ta_arm32=-pg run
$ xtest 1019
D/LD: ldelf:134 Loading TA 5b9e0e40-2636-11e1-ad9e-0002a5d5c51b
E/LD: __resolve_sym:61 Symbol type not supported
E/TC:? 0 init_with_ldelf:232 ldelf failed with res: 0xffff000a
* regression_1019 Test dynamically linked TA
regression_1000.c:1502: [...] TEEC_ERROR_NOT_SUPPORTED
This commit adds STT_NOTYPE to the supported types, handled the same way
as STT_OBJECT and STT_FUNCTION.
