Subject: configure: Replace obsolete AC_TRY_LINK with AC_LINK_IFELSE
X-Git-Tag: glibc-2.34~928
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e9e7f24543e6d1b0a31641f144697e261df6ccd7;p=thirdparty%2Fglibc.git

configure: Replace obsolete AC_TRY_LINK with AC_LINK_IFELSE

This patch replaces obsolete AC_TRY_LINK with AC_LINK_IFELSE.
It has been confirmed that GNU 'autoconf' 2.69 doesn't change the
'configure' file and suppressed obsolete warning.
