* libtool.m4 (AC_LIBTOOL_PROG_CC_C_O): Some compilers (e.g. Intel

Linux icc compiler) write temporary files to the current
directory. These compilers do support -c and -o simultaneously but
wrongly fail the test due to the failure to create temporary
files. It is incorrect to penalize compilers which write temporary
files to the current directory so the 'chmod -w .' is therefore
removed.
