I have a linker error, when compiling small vibe.d project with DUB:
dmd -of/tmp/dub/2648184025/mart /tmp/dub/2648184025/temp.o -L-Wl,-z,relro -L-L/usr/lib6464 -L-lssl -L-lcrypto -L-ldl -L-lz -L-levent_pthreads -L-levent -g
/usr/bin/ld: unrecognized option '-Wl,-z,relro'
DUB is built from the sources (the latest master branch)
