I tried two different gcc's from Debian.  The errors were:

hidden symbol `__stack_chk_fail_local' in [...] is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output

and even wierder:

/usr/lib/libc_nonshared.a(elf-init.oS)(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x0): 
In function `__i686.get_pc_thunk.bx': multiple definition of 
`__i686.get_pc_thunk.bx'
