 >Environment:
 Solaris 2.6 on SPARC Ultra1
 >Description:
 The "new" method to detect the endianness by
 fgrepping the object file containing a magic string
 ("BIGenDianSyS","LiTTleEnDian")
 did NOT work on Solaris stock fgrep.
 
 This seems to be that because the string is delimited by
 NUL (0x00), not LF (0x0a).
 >How-To-Repeat:
 cd tests
 ./testsuite 77
 >Fix:
 The attached patch adds LF (0x0a) around the magic string
 which fixed the problem.
 The patch is for 2.53 but the latest 2.57 seems to have
 not changed, having a same issue.
