   ../../exec/exec.c: In function `check_elf_phdr':
   ../../exec/exec.c:931: error: `PT_GNU_STACK' undeclared (first use in this 
   ../../exec/exec.c:931: error: (Each undeclared identifier is reported only 
   ../../exec/exec.c:931: error: for each function it appears in.)

You are using a old version of the GNU C library.  PT_GNU_STACK got
introduced into glibc by the following:

,----[ libc/ChangeLog ]
| 2003-06-05  Roland McGrath  <roland@redhat.com>
|         * elf/elf.h (PT_GNU_STACK): New macro.

Not sure what the correct fix is.  One way is to have configure.in
check for PT_GNU_STACK, and then do:

| #defin PT_GNU_STACK ...
| #endif

Somewhere in a config.h header, but this requires the use of
autoheader.  Roland or Marucs, what would you prefer?

Anyway, for the impatient, here is a patch that will make exec compile
