sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c defines posix_fadvise64 as a strong alias for posix_fadvise (for !SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) - i.e., for static linking, which is the case when this matters), but it should be a weak alias. This patch makes it a weak alias. Tested for MIPS that this fixes the observed linknamespace test failures. [BZ #17796] * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c [!SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3)] (posix_fadvise64): Define as weak alias not strong alias.
