Subject: [PATCH] configure.ac: autodetect need for external libintl

uclibc-ng and macos standard libraries don't provide libintl
facilities. As a result build fails as
(x86_64-gentoo-linux-uclibc example):

```
...
gcc  -g -O2   -o rpcgen rpc_clntout.o rpc_cout.o rpc_hout.o rpc_main.o rpc_parse.o rpc_sample.o rpc_scan.o rpc_svcout.o rpc_tblout.o rpc_util.o
/usr/lib/gcc/x86_64-gentoo-linux-uclibc/9.2.0/../../../../x86_64-gentoo-linux-uclibc/bin/ld: rpc_main.o: in function `usage':
/root/rpcsvc-proto/rpcgen/rpc_main.c:1403: undefined reference to `libintl_gettext'
/usr/lib/gcc/x86_64-gentoo-linux-uclibc/9.2.0/../../../../x86_64-gentoo-linux-uclibc/bin/ld: /root/rpcsvc-proto/rpcgen/rpc_main.c:1404: undefined reference to `libintl_gettext'
...
```

The change is simple: add gettext m4 macros to detect need
for libintl and link to an external library if needed.

Tested on x86_64-glibc and x86_64-uclibc-ng.
