When attempting to check for `magic_open` in libmagic (aka file),
linking can fail as libmagic and zlib may have been statically built:
configure:20636: .../arm-linux-gcc -std=gnu99 -o conftest ... conftest.c
-lmagic -lpthread >&5
conftest.c:42:1: warning: function declaration isn't a prototype
[-Wstrict-prototypes]
...
.../sysroot/usr/lib/libmagic.a(compress.o): In function `uncompresszlib':
compress.c:(.text+0x190): undefined reference to `inflateInit_'
compress.c:(.text+0x1a8): undefined reference to `inflateInit2_'
compress.c:(.text+0x1bc): undefined reference to `inflate'
compress.c:(.text+0x1d4): undefined reference to `inflateEnd'
compress.c:(.text+0x1fc): undefined reference to `zError'
collect2: error: ld returned 1 exit status
...
configure:20645: result: no
configure:20654: error: missing required library 'libmagic'
The following adds the rpm-dependent zlib library to ensure the check
for `magic_open` can find the dependent decompression methods.
