config: add AM_PROG_CC_C_O for per-target compilation flags
The use of per-target compilation flags with C sources requires that the macro AM_PROG_CC_C_O be called from configure.ac If the C compiler does not accept the -c and -o options simultaneously, define NO_MINUS_C_MINUS_O. This macro actually tests both the compiler found by AC_PROG_CC, and, if different, the first cc in the path. The test fails if one fails. This macro was created for GNU Make to choose the default C compilation rule. Signed-off-by: Gaetan Nadon <memsize@videotron.ca>
