Jerin Jacob 11b57c6980 eal: fix error string function
errno_autotest testcase were failed since
commit 5d7b673d5f ("mk: build with _GNU_SOURCE defined by default")
RTE>>errno_autotest
rte_strerror: 'Unknown error 11',
strerror: 'Resource temporarily unavailable'
Test Failed

There are two different version of strerror_t() based on
_GNU_SOURCE definition.

/* XSI-compliant */
int strerror_r(int errnum, char *buf, size_t buflen);

/* GNU-specific */
char *strerror_r(int errnum, char *buf, size_t buflen);

Since the GNU-specific version returns char* the exiting "if"
condition around the strerror_r fails.

Switching back to XSI-compliant version to allow

a) Portable strerror_r() usage as musl c library uses
non GNU speficic version
https://git.musl-libc.org/cgit/musl/tree/src/string/strerror_r.c

b) Based on strerror_r(3) man page, it is possible that GNU-specific
version need not use char *buf to fill error message instead it
can use the immutable static string from the library and return it.

note from strerror_r(3) man page:

The GNU-specific strerror_r() returns a pointer to a string containing
the error message.  This may be either a pointer to a string that the
function stores in buf, or a pointer to some (immutable)
static string (in which case buf is unused).
