Subject: ldbl-128ibm: Let long double files have specific compiler flags
X-Git-Tag: glibc-2.32~520

ldbl-128ibm: Let long double files have specific compiler flags

Soon, powerpc64le will need to provide extra compiler flags to the long
double files in order to continue to build using the IBM 128-bit
extended floating point type as long double.
