[PATCH] erofs-utils: dump: fix linking when using --with-selinux

[David Michael <fedora.dm0@gmail.com>]

The libselinux functions selabel_open and selabel_close are called
by lib/config.c, so include libselinux in CFLAGS and LIBS to fix
building dump.erofs.

Hi,

I tried building the dev branch with SELinux support and got this:

/bin/sh ../libtool  --tag=CC   --mode=link x86_64-pc-linux-gnu-gcc -Wall -Werror -I../include -O2 -pipe  -Wl,-O1 -Wl,--as-needed -o dump.erofs dump_erofs-main.o ../lib/liberofs.la -luuid  
libtool: link: x86_64-pc-linux-gnu-gcc -Wall -Werror -I../include -O2 -pipe -Wl,-O1 -o dump.erofs dump_erofs-main.o  -Wl,--as-needed ../lib/.libs/liberofs.a -luuid
/usr/lib/gcc/x86_64-pc-linux-gnu/10.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../lib/.libs/liberofs.a(liberofs_la-config.o): in function `erofs_exit_configure':
config.c:(.text+0xe2): undefined reference to `selabel_close'
/usr/lib/gcc/x86_64-pc-linux-gnu/10.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: ../lib/.libs/liberofs.a(liberofs_la-config.o): in function `erofs_selabel_open':
config.c:(.text+0x180): undefined reference to `selabel_open'
collect2: error: ld returned 1 exit status

Should it just link libselinux to fix the build?

Thanks.

David
