+Subject: [PATCH] use AC_COMPILE_IFELSE rather than AC_TRY_RUN
+
+AC_TRY_RUN relys on executing the test, not working while cross
+compiling. Thus a hard wired value for the cross compilation must and is
+used.
+
+Switching to AC_COMPILE_IFELSE just tries to compile the test program
+which has the save effect and works even in the cross compiling
+scenario.
+
+This patch uses AC_COMPILE_IFELSE for these tests:
+"--enable-profiling, enable C-level code profiling"
+"whether $CC accepts -fno-strict-aliasing"
+"whether $CC accepts -OPT:Olimit=0"
+"whether $CC accepts -Olimit 1500"
