Description
Steps (on loongarch64 platforms):
$ bash configure --with-boot-jdk=../jdk-24 --with-jvm-variants=zero
$ make images

Errors:

Cause:
After https://bugs.openjdk.org/browse/JDK-8329004, the following code was added. 

#ifndef PNG_LOONGARCH_LSX_OPT
#  if defined(__loongarch_sx)
#     define PNG_LOONGARCH_LSX_OPT 1
#  else
#     define PNG_LOONGARCH_LSX_OPT 0
#  endif
#endif

Some compilers on LoongArch64 platforms enable __loongarch_sx, which causes PNG_LOONGARCH_LSX_OPT to be defined and an undefined error occurs. Refer to https://bugs.openjdk.org/browse/JDK-8078245, add -DPNG_LOONGARCH_LSX_OPT=0 to LIBSPLASHSCREEN_CFLAGS flags.
Comments
[jdk25u-fix-request] Approval Request from Ao Qi The backport is clean. This patch fixes a build issue with the zero build on some loongarch platforms. This patch affects a client-libs CFLAGS macro definition, which only works on LoongArch. The loongarch zero builds passed.
