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,
even if it prints `undefined`. This is arguably a bug in the Makefile,
but even so, getconf shouldn't report that unsupported variables are
valid.

de28c8bfa7 use only one getconf header
this simplifies the getconf.sh script and handling parallel make

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.

Thanks k0ga for the suggestion!

Uncomment the entries if your system supports them.

05996b997c Add getconf(1)
The logic is simple, it's just a pain in the ass to fill the
data-structures.
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.
