package/go: disable stack protector for cgo
Browse files Browse the repository at this point in the history
Enabling the C stack protector for Cgo causes a build failure on i386:

runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel
runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel
runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel
runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel
runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel
runtime/cgo(.text): relocation target __stack_chk_fail_local not defined
runtime/cgo(.text): relocation target __stack_chk_fail_local not defined

Add: CGO_CFLAGS=-fno-stack-protector

golang/go#52919

Set CGO_CFLAGS and other flags while building Go with make.bash as well.
