Fix a bug in libtool's ltmain.sh. On Cygwin the "$output.exp" expression
expands to a full path name. Substitute $outputname.exp" instead and it makes a viable temporary file name. This gets around the problem with lli on Cygwin linking but not having any "C" library functions linked into it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19123 91177308-0d34-0410-b5e6-96231b3b80d8

This should correctly update the macro definitions in the libtool m4
files to match the version of autoconf that LLVM uses. This converts
AC_HELP_STRING to AS_HELP_STRING and AC_TRY_LINK to AC_LINK_IFELSE, amongst
other things. You may need to manually adjust the files.
