GHC cc phase doesn't add -framework-path flags

When compiling a C file with ghc, framework search paths (-framework-path) are not passed to gcc. For example, compiling the test file rl.c with GNUreadline.framework stored in $HOME/Library/Frameworks:

$ cat rl.c 
#include <stdio.h>
#include <GNUreadline/readline/readline.h>

int main(void) {
    char *line = readline("Enter a line: ");
    if (line) printf("Line was:%s\n",line);
    return 0;
}
$ gcc -F$HOME/Library/Frameworks -framework GNUreadline rl.c
$ ghc -framework-path $HOME/Library/Frameworks -framework GNUreadline rl.c

rl.c:2:43:
     error: GNUreadline/readline/readline.h: No such file or directory
rl.c: In function 'main':

rl.c:5:0:  warning: implicit declaration of function 'readline'

rl.c:5:0:
     warning: initialization makes pointer from integer without a cast

This bug was found by Christian Maeder when creating a potential fix for #1395 (closed). Discussion in that task is revolving around making GHC add $HOME/Library/Frameworks automatically; but regardless of that task's resolution, we should fix the above behavior.
