runtime/cgo: add -fno-stack-protector to CFLAGS
Browse files Browse the repository at this point in the history
Some compilers default to having -fstack-protector on, which breaks
when using internal linking because the linker doesn't know how to
find the support functions.

Fixes #52919
Fixes #54313
