- abort with notice when tcc_relocate() is called with the
former two-step method
- support backtrace & bcheck not only with tcc_run() but also
for directly called functions from tcc_get_symbol(); enable
witn 'tcc_set_options("-bt/-b");'
- move struct rt_context and debug sections into compiled code
for TCC_OUTPUT_MEMORY also
- protect access (g_rc) with semaphore
Also:
- add armv7/aarch4/riscv64 github tests (qemu emulated)
- win32/build-tcc.bat: build cross compiler only with -x
