Compile with FULL RELRO

[raffaem]

I'm trying to package the pre-compiled libraries for the AUR.

But namcap laments those files lack FULL RELRO:

➜ namcap sqlean-libs-0.21.8-1-x86_64.pkg.tar.zst 
sqlean-libs W: ELF file ('usr/lib/sqlean/crypto.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/define.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/fileio.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/fuzzy.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/ipaddr.so') lacks FULL RELRO, check LDFLAGS.

sqlean-libs W: ELF file ('usr/lib/sqlean/regexp.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/sqlean.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/stats.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/text.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/unicode.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/uuid.so') lacks FULL RELRO, check LDFLAGS.
sqlean-libs W: ELF file ('usr/lib/sqlean/vsv.so') lacks FULL RELRO, check LDFLAGS.

Which is confirmed by checksec:

➜ checksec --file=./src/crypto.so
RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH  Symbols     FORTIFY Fortified   Fortifiable FILE
Partial RELRO   Canary found      NX enabled    DSO             No RPATH   No RUNPATH   127 Symbols  Yes    1       ./src/crypto.so

I believe they should be compiled with -z,relro,-z,now gcc options. See for example: https://www.redhat.com/en/blog/hardening-elf-binaries-using-relocation-read-only-relro
