I tried adding LDFLAGS="%{build_ldflags}" but then I get:
cc -O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches
-pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2
-Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
-fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1
-m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection
-fcf-protection --Wl,-z,relro -Wl,--as-needed -Wl,-z,now
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld -s -lfuse chunkfs.o utils.o
-o chunkfs
make: *** Waiting for unfinished jobs....
cc: error: unrecognized command-line option '--Wl,-z,relro'
