[LTP] [PATCH 1/2] cacheflush: enable cacheflush syscall for other architectures.

[LTP] [PATCH 1/2] cacheflush: enable cacheflush syscall for other architectures.

[Carmelo AMOROSO]

From: Francesco Rundo <francesco.rundo@st.com>

'cacheflush' syscall is available for other architectures than mips (i.e. SH4)
as originally the testcase was assuming.
Rely upon the availability of __NR_syscall numbers from kernel headers.
