These are all useless and only make debugging (very) 
difficult.

This is useless on Linux and friends.

Why? This is only needed with external libraries 
that you don't enable.

This definitely has an effect, please be warned that 
it also has sometimes unexpected results (like disabling 
the png codec).

This is ok if you know (exactly) what you are doing, 
note that as far as I am concerned the resulting 
binaries are unsupported.

See --disable-yasm, these are debug options that 
you normally should not use.

If inline asm is really broken with gcc 5.1 (this 
is not completely unexpected), please downgrade to 
a slightly older version (and please report this 
to gcc).
