Michael Forney eb74f374f2 getconf: Add an explicit return at the end of main
ISO C does not require that main() have an explicit return value

Michael Forney c225d88d49 getconf: Report invalid variables as errors
Printing `undefined` to stdout means that the variable is valid but not
set. Instead, report an error in this case.

linux 4.13 appends the result of `getconf LFS_CFLAGS` to HOSTCFLAGS,

but even so, getconf shouldn't report that unsupported variables are

Roberto E. Vargas Caballero 136f012d23 Remove ifdef hell from getconf.c
Every system is going to have a different configuration
so the only solution is to put an ifdef guard for every
value.  To do this, we generate the header at compile time
with a shell script.

FRIGN 05996b997c Add getconf(1)
The logic is simple, it's just a pain in the ass to fill the
Some lines had to be commented out, as glibc/musl apparently
have not fully implemented the mandatory variables for the
2013 corrigendum of POSIX 2008.

Also added a manpage and the necessary entries in README.

I also removed it from the TODO.
