gnu: Simplify the use of --with-long-double-128.
Fixes <https://bugs.gnu.org/48825>. In short, this change adds the hard-coded "--with-long-double-128" configure option in one place and removes it from two other places. This changes and simplifies the use of this option for various architectures that start with the string "powerpc". * gnu/packages/gcc.scm (gcc-configure-flags-for-triplet): Add a clause for targets starting with "powerpc64le-" or "powerpc-" which adds the "--with-long-double-128" option. This causes any package using this procedure to be built using this new option on these architectures. In particular, this affects the gcc package and the gcc-final package, in addition to all the other versions of GCC defined in (gnu packages gcc). * gnu/packages/commencement.scm (gcc-boot0)[#:configure-flags]: Remove the code that adds the "--with-long-double-128" configure option for all architectures starting with "powerpc", since it is now redundant on the architectures where it is needed. The gcc-boot0 package uses (and adds to) the gcc package's configure options. This means that the above change in gcc.scm is sufficient to ensure that the gcc-boot0 package's configure options will include "--with-long-double-128" on powerpc64le and powerpc architectures. Additionally, since the option is apparently not required on the big-endian powerpc64 architecture, this change also has the nice effect of omitting the option in that case. * gnu/packages/cross-base.scm (cross-gcc-arguments)[#:configure-flags]: Remove the code that adds the "--with-long-double-128" configure option for powerpc64le, since it is now redundant. The cross-gcc-arguments procedure uses (and adds to) the configure options of its xgcc argument (a package). This means that regardless of which gcc from gcc.scm is used as the xgcc, the above change in gcc.scm is sufficient to ensure that the cross-gcc-arguments procedure's configure options will include "--with-long-double-128" on the powerpc64le and powerpc architectures.
