Bump Buildroot version and select GCC 14 with binutils 2.42

This commit intends to avoid a recent glibc bug that mistakenly uses 64-bit
time on 32-bit machines.

Consider the Linux `input_event` structure:

struct input_event {
	struct timeval time;
	__u16 type;
	__u16 code;
	__s32 value;
};

On RV32 Linux, the total size of this structure should be 16 bytes (8+2+2+4).
However, due to a known glibc bug [2] that incorrectly utilizes the 64-bit time
type, the actual size of the structure becomes 24 bytes (16+2+2+4).

Without this fix, the bug would affect the usage of DirectFB2 in the semu
project. Fortunately, upgrading the toolchain version resolves the issue.
