Because we already wrapped ECL executable with CPATH and LIBRARY_PATH
environment variable. so any compilation done in ECL can find the
library and header.
If some 3-rd party program want to link with ECL(If they use ECL as
thier extension language). Compiler will failed to find gmp, libgc etc.
A simple example here, start with `guix environment --ad-hoc ecl`
```
chino@asus-laptop:~/tmp$ cat test.c
#include <ecl/ecl.h>
int main() {
cl_boot(0, NULL);
return 0;
}
chino@asus-laptop:~/tmp$ CFLAGS="$(ecl-config --cflags) $(ecl-config --ldflags) $(ecl-config --libs)"
chino@asus-laptop:~/tmp$ LANG=en_US.utf-8 gcc -c test.c -o test $CFLAGS
