commit 7fa1d9462baabc5a1058efc13a48444af4678acf
Author: Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
Date:   Thu Jun 22 15:47:16 2017 -0300

    Add libio-mtsafe flags to the build of strfromf128
    
    Similar to the other functions in the strfrom class, strfromf128 calls
    __printf_fp in order to convert the floating-point value to characters.
    This requires the value of IO_MTSAFE_IO.
    
    Tested for powerpc64le and s390x.
    
    	* sysdeps/ieee754/float128/Makefile (CFLAGS-strfromf128.c): Add
    	$(libio-mtsafe) to get the value of IO_MTSAFE_IO.

    Prepare the manual to display math errors for float128 functions
    
    When float128 support gets enabled for powerpc64le, the ULP errors for
    float128 functions need to be presented in the manual.  This patch adds
    support for displaying them.
    
    Tested for powerpc64le and s390x.
    
    	* manual/libm-err-tab.pl (@all_floats, %suffices, parse_ulps):
    	Enable generation of float128 entries on the error table.

    Include libc-header-start.h in include/float.h
    
    The file include/float.h uses the macro __GLIBC_USE to test for TS 18661-3
    support.  Such macro is provided by bits/libc-header-start.h, so include it
    to get the definition.
    
    Tested for powerpc64le and s390x.
