The releases/gcc-10 branch has been updated by Michael Meissner

https://gcc.gnu.org/g:641b407763ecfee5d4ac86d8ffe9eb1eeea5fd10

commit r10-10486-g641b407763ecfee5d4ac86d8ffe9eb1eeea5fd10
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Sat Mar 5 20:11:38 2022 -0500

    Define __SIZEOF_FLOAT128__ and __SIZEOF_IBM128__.

    Define the sizes of the PowerPC specific types __float128 and __ibm128 =
if
those
    types are enabled.

    This patch will define __SIZEOF_IBM128__ and __SIZEOF_FLOAT128__ if the=
ir
    respective types are created in the compiler.  Currently, this means bo=
th
of
    these will be defined if float128 support is enabled.  But at some poin=
t in
    the future, __ibm128 could be enabled without enabling float128 support=
 and
    __SIZEOF_IBM128__ would be defined.
