The HOSTCC value defaults to the value of CC if not cross-compiling.
If cross-compiling, HOSTCC defaults to "gcc".

HOSTCFLAGS, HOSTLDFLAGS, and HOSTLIBS are also given sensible default
values.

latter case, foo is also disabled.

Some compilers output a new rule for each dependency.  We must prefix
each one with the directory name.

Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.
