[jdk11u-dev] RFR: 8293887: AArch64 build failure with GCC 12 due to maybe-uninitialized warning in libfdlibm k_rem_pio2.c

[SendaoYan]

Hi,
  This is backport of [JDK-8293887](https://bugs.openjdk.org/browse/JDK-8293887). It's not clean backport, because the file `make/lib/CoreLibraries.gmk` has been moved to `make/modules/java.base/lib/CoreLibraries.gmk`

Testing list:

- [ ] linux x64 gcc10
- [ ] linux x64 gcc13
- [ ] linux aarch64 gcc10
- [ ] linux aarch64 gcc13
- [ ] linux riscv64 gcc13
