commit 4fb4e7e821e36180835bf88e363f9f13b5797e3a (HEAD)
Author: Florian Weimer <fweimer@redhat.com>

    csu: Always use __executable_start in gmon-start.c

    Current binutils defines __executable_start as the lowest text
    address, so using the entry point address as a fallback is no
    longer necessary.  As a result, overriding <entry.h> is only
    necessary if the entry point is not called _start.

    The previous approach to define __ASSEMBLY__ to suppress the
    declaration breaks if headers included by <entry.h> are not
    compatible with __ASSEMBLY__.  This happens with rseq integration
    because it is necessary to include kernel headers in more places.
