[dpdk-dev] [PATCH] eal/windows: fix build warnings in MinGW

[Tal Shnaiderman <talshn@nvidia.com>]

the strncasecmp marco defined in rte_os_shim.h is already
defined in MinGW-w64, as a result the compiler prints out
the warning below on function redefinition whenever compiling
a file including the header.

..\lib/librte_eal/windows/include/rte_os_shim.h:21:
warning: "strncasecmp" redefined
#define strncasecmp(s1, s2, count) _strnicmp(s1, s2, count)

Fixed by defining the marco only to the clang compiler.

Fixes: 45d62067c237 ("eal: make OS shims internal")
