[Bug ld/878] New: -pie broken

Here's the test case:

$ echo 'main(){}' | gcc -B/opt/binutils/head/bin/ -x c -fpie -pie -
/usr/lib/libc_nonshared.a(elf-init.oS): In function `__libc_csu_init':
elf-init.c:(.text+0x1d): undefined reference to `__init_array_end'
elf-init.c:(.text+0x23): undefined reference to `__init_array_start'
/usr/lib/libc_nonshared.a(elf-init.oS): In function `__libc_csu_fini':
elf-init.c:(.text+0x79): undefined reference to `__fini_array_end'
elf-init.c:(.text+0x7f): undefined reference to `__fini_array_start'
collect2: ld returned 1 exit status

It seems this change might be responsible:

2005-03-22  H.J. Lu  <address@hidden>

        * emultempl/elf32.em (gld${EMULATION_NAME}_provide_bound_symbols): New
        (gld${EMULATION_NAME}_finish): Call
        gld${EMULATION_NAME}_provide_bound_symbols to provide
        __preinit_array_start, __preinit_array_end, __init_array_start,
        __init_array_end, __fini_array_start and __fini_array_end.

        * scripttempl/elf.sc: Don't provide __preinit_array_start,
        __preinit_array_end, __init_array_start, __init_array_end,
        __fini_array_start nor __fini_array_end.

Additionally, there seems to be nothing in the testsuite testing -pie (apart
from frv) which of course is not ideal.
