Building with go lacks FULL RELRO, check LDFLAGS [solved]

I created a PKGBUILD for shonenjump which is written in go.  Not being experienced with go, I fear my build command (line 18) is not right.

go build -v -buildmode=pie -ldflags "-extldflags \"$LDFLAGS\""

Although the package builds successfully, namcap complains:

shonenjump W: ELF file ('usr/bin/shonenjump') lacks FULL RELRO, check LDFLAGS.

EDIT: go build -buildmode=pie -ldflags "-linkmode=external -extldflags=$LDFLAGS"

I was having the same problem and took me a long time to find the answer. Those 2 pages will help and make your builds pass namcap without a single error
