Hello,

the attached patch adds a check to configure to see whether the compiler
really exists. If configure is called with --cc , but the given compiler
doesn't exist, configure currently fails without giving a good reason.

(In my case I ran "./configure --cc=gcc-3.4" but gcc-3.4 doesn't exist
on the system; configure then told me that it couldn't find SDL, without
hinting at the real reason. The little notice that the endian check
failed as well escaped my eyes :-)

Regards,
Oliver Gerlich
