13 bool "Create static libraries only and link statically"
16 Useful for debugging of dynamic linker problems. Be aware of the fact, that uClibc and glibc
17 still requires libgcc_so.so.1 for pthread_cancel. Glibc also requires libnss_*.so libraries
18 at runtime. Full static builds are only supported for musl libc.
