This change fixes a segmentation fault that occurs on musl-based systems
when using c-archive (or c-shared with LD_PRELOAD). The issue
was caused by uninitialized argv and envp, which led to crashes at runtime.

This fix ensures that both argv and envp are correctly initialized,
preventing the segmentation fault.

While this fix addresses crashes due to missing argv and envp, it does
not address the error described in issue golang#54805, where a c-shared library
loaded with dlopen triggers an error related initial-exec access to
TLS objects [1] in a dynamically loaded library.
