Well, generally, it means that you are compiling for a different
architecture than what you are running. For example, it is possible
to compile for AMD64 CPUs from a P4 host, or vice-versa. However,
since you are not doing that, it means your toolchain is broken in
some way.
The way autoconf (the ./configure script) checks for this is that it
compiles a very simple program. This program is:
#line 1880 "configure"
#include "confdefs.h"
main(){return(0);}
It then compiles this program. If the program compiles, configure
decides that gcc works. If the program doesn't run, it decides that
you are cross compiling. So, let's try this manually.
Save the above lines to a file, call it conftest.c. The build it with
gcc -O2 -march=pentium4 -fomit-frame-pointer -L/usr/X11R6/lib -ltiff
-L/usr/lib -o conftest conftest.c
If the compile complets without error, try running the program with:
conftest && echo "works"
