### 'ldd' of resulting Quota.so:
#

[root@5210r ~]# LC_ALL=C ldd /usr/lib64/perl5/vendor_perl/auto/Quota/Quota.so
        linux-vdso.so.1 (0x00007ffc653d6000)

#
### Fix:
#

After running "perl Makefile.PL" edit the resulting Makefile and change the "MakeMaker const_config section" to this:
# --- MakeMaker const_config section:

# These definitions are from config.sh (via /usr/lib64/perl5/Config.pm).
# They may have been overridden via Makefile.PL or on the command line.
AR = ar
CC = gcc
CCCDLFLAGS = -fPIC
CCDLFLAGS = -Wl,--enable-new-dtags -Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -ltirpc
DLEXT = so
DLSRC = dl_dlopen.xs
EXE_EXT =
FULL_AR = /usr/bin/ar
LD = gcc
LDDLFLAGS = -lpthread -shared -Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L/lib64 -ltirpc
LDFLAGS = -Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -fstack-protector-strong -ltirpc -L/lib64
LIBC = libc-2.28.so
LIB_EXT = .a
OBJ_EXT = .o
OSNAME = linux
OSVERS = 4.14.0-49.el7a.noaead.x86_64
RANLIB = :
SITELIBEXP = /usr/local/share/perl5
SITEARCHEXP = /usr/local/lib64/perl5
SO = so
VENDORARCHEXP = /usr/lib64/perl5/vendor_perl
VENDORLIBEXP = /usr/share/perl5/vendor_perl

That will then build just fine. This can perhaps be set on the command line during configure, but that didn't seem to work well enough for me.
