[LTP] [PATCH] read_all: Define FNM_EXTMATCH if not already (like under musl).

[Daniel Díaz]

With musl, FNM_EXTMATCH is not defined:
| read_all.c: In function 'read_test':
| read_all.c:201:41: error: 'FNM_EXTMATCH' undeclared (first use in this function); did you mean 'FNM_NOMATCH'?
|   if (exclude && !fnmatch(exclude, path, FNM_EXTMATCH)) {
|                                          ^~~~~~~~~~~~
|                                          FNM_NOMATCH
| read_all.c:201:41: note: each undeclared identifier is reported only once for each function it appears in
| <builtin>: recipe for target 'read_all' failed
| make[4]: *** [read_all] Error 1
