Running `autoreconf -vf -Wall' in the sim directory shows errors about the use of obsolete macros. This patch fix the issues with macros used or defined in the sim directory. However, it doesn't fix all warnings. There's 1 autoconf warning from `config/pkg.m4', and many automake warnings about target shadowing. It cuts a lot of the noise down and makes an upgrade to autoconf 2.71+ easier. - Replace AC_CANONICAL_SYSTEM by AC_CANONICAL_TARGET https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fCANONICAL_005fSYSTEM-1997 - Replace AC_TRY_COMPILE by AC_COMPILE_IFELSE https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fTRY_005fCOMPILE-2203 - Replace AC_ERROR by AC_MSG_ERROR https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fERROR-2034 - Remove AC_TYPE_SIGNAL and replace `RETSIGTYPE' by `void' in the source https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fTYPE_005fSIGNAL-2213 - Remove AC_STRUCT_ST_BLKSIZE, it's already covered by a AC_CHECK_MEMBERS call https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fSTRUCT_005fST_005fBLKSIZE-2176 - Remove AC_STRUCT_ST_RDEV, it's already covered by a AC_CHECK_MEMBERS call https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/ Obsolete-Macros.html#index-AC_005fSTRUCT_005fST_005fRDEV-2180 - Remove AC_STRUCT_ST_BLOCKS.
