commit 3bdc16ce98295463c071192eab2ec611a8edc508

Author: Mark Wielaard <mjw@redhat.com>

    elflint: Add two more symbols to gnuld list of allowed bad values.

    Add __bss_start and __TMC_END__ to the list of symbols allowed to have

    out of section values because of the following GNU ld bug:

    http://sourceware.org/bugzilla/show_bug.cgi?id=13621.

    Allow them to appear in either .symtab or .dynsym, but only when they

    are zero sized. It is impossible to define a general rule for this bug,

    but this should catch most common issues that are mostly harmless

    because the symbols signify the removed section was empty to being with.

    This catches at least all symbols often flagged in the tests.

    elflint.c (check_symtab): Add __bss_start__ to the list of allowed symbols.

    Some architectures (ARM) use __bss_start__ instead of __bss_start.
