>Description:
There's a number of AC_CHECK_FUNCS instances with incorrect
list of functions to check, e.g.:

AC_CHECK_FUNCS([bswap16, bswap32, bswap64] ...)

The list of functions should be space separated, not comma separated.
This error results in wrong configure tests.

checking for bswap16,... no
checking for bswap32,... no
checking for bswap64... no

The C code for the test uses incorrect name with the trailing comma
all over the place, e.g:

char bswap16, ();

>How-To-Repeat:
Check $(OBJDIR)/tools/compat/config.log of any build.

>Fix:
Drop those commas.
