Fix FTBFS on ARM on GCC 4.7.0
...
GCC v4.7.0, as found in Fedora 17 and newer, fails to build mosh on
ARM because of a narrowing warning, which is then promoted to an error
by -Werror. This error message is new, and did not occur under
previous versions of GCC.
This patch corrects this error by explicitly casting to the desired
datatype the return value of the offending code, the result of a macro
from glibc to implement htobe16().

Check compiler support for -fno-default-inline and -pipe
...
clang was spewing warnings about the unrecognized -fno-default-inline. (Oddly,
it warns only with -c, not when compiling directly to an executable.) For
completeness we also check -pipe, even though clang is OK with that one.
It should be fine to omit either flag. gcc -fno-default-inline drops the
implicit 'inline' annotation on functions defined inside a class scope, but
'inline' is only a hint anyway. -fno-default-inline does not change linkage.
-pipe is merely a compile speed optimization.
