Why start "thinking" when it takes one minute to lookup the docs
https://docs.oracle.com/cd/E88353_01/html/E37853/u--start-crt-compiler-7.html
and another minute to try with a hello.c that includes that function.

According to
https://docs.oracle.com/cd/E26502_01/html/E26507/chapter6-42444.html
"_DYNAMIC" seems to be a section symbol that the linker should provide.
Maybe as in tccelf.c:tcc_add_linker_symbols()
