[Buildroot] [git commit] package/php: remove CFLAGS for OPcache extension

commit: https://gitlab.com/buildroot.org/buildroot/-/commit/623ed7c8c7a01f493427164c98bcc731d035f45a
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/master

Buildroot commit aedf131da66d2f2ebce64788deab07be17ce33eb bumped the
package to 8.5.0 which made opcache a mandatory dependency but kept the
CFLAGS added in 2015 with buildroot commit
e05476491720f96fcbeb926b4599d111efb598a6.

As it turns out we need to remove the CFLAGS to fix the build with the
bootlin-aarch64-glibc-old defconfig as detected by the Gitlab pipelines:

ext/opcache/shared_alloc_posix.o: In function `create_segments':
shared_alloc_posix.c:(.text+0xcc): undefined reference to `shm_open'
shared_alloc_posix.c:(.text+0x11c): undefined reference to `shm_unlink'
shared_alloc_posix.c:(.text+0x19c): undefined reference to `shm_unlink'
shared_alloc_posix.c:(.text+0x1b8): undefined reference to `shm_unlink'

as they seem to disturb the detection of librt.

It is unclear which upstream commits added since 2015 fixed the original
problem so a backport to LTS branches is not advised.
