Add the --enable-single-binary option to the configure file.
When enabled, this option builds a single binary file containing
the selected tools. Which tool gets executed depends on the value
of argv[0] which can be set implicitly through symlinks to the
single program.
This setup reduces significantly the size of a complete coreutils
install, since code from lib/libcoreutils.a is not duplicated in
every one of the more than 100 binaries. Runtime overhead is
increased due to more dynamic libraries being loaded, and extra
initialization being performed for all utils. Also initially
a larger binary is loaded from storage, though this is usually
alleviated due to caching and lazy mmaping of unused blocks,
and in fact the single binary should have better caching
characteristics.
Comparing the size of the individual versus single binary on x86_64:
$ cd src
$ size coreutils
$ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
text data bss dec hex filename
1097416 5388 88432 1191236 122d44 src/coreutils
4901010 124964 163768 5189742 4f306e (TOTALS)
Storage requirements are reduced similarly:
$ cd src
$ du -h coreutils
$ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
grep -Ev '(coreutils|libstdbuf)') | tail -n1
1.2M coreutils
5.3M total
When installing, the makefile will create either symlinks or
shebangs based on the --enable-single-binary setting, for
each configured tool. In this way, all the tools are still
callable individually, but they are all implemented by the same
"coreutils" binary installed on the same directory.

one to the other if needed).
