The aarch64 uses 'trad' for traditional tls and 'desc' for tls
descriptors, but unlike other targets it defaults to 'desc'. The
gnutls2 configure check does not set aarch64 as an ABI that uses
TLS descriptors, which then disable somes stests.
Also rename the internal machinery fron gnu2 to tls descriptors.
Checked on aarch64-linux-gnu.

\`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
|
||
|
||
Usage: $0 [OPTION]... [VAR=VALUE]...
|
||
|
||
To assign environment variables (e.g., CC, CFLAGS...), specify them as
|
||
VAR=VALUE. See below for descriptions of some of the useful variables.
|
||
|
||
Defaults for the options are specified in brackets.
|
||
|
||
Configuration:
|
||
-h, --help display this help and exit
|
||
--help=short display options specific to this package
|
||
--help=recursive display the short help of all the included packages
|
||
-V, --version display version information and exit
|
||
-q, --quiet, --silent do not print \`checking ...' messages
|
||
--cache-file=FILE cache test results in FILE [disabled]
|
||
-C, --config-cache alias for \`--cache-file=config.cache'
|
||
-n, --no-create do not create output files
|
||
--srcdir=DIR find the sources in DIR [configure dir or \`..']
|
||
|
||
Installation directories:
|
||
--prefix=PREFIX install architecture-independent files in PREFIX
|
||
[$ac_default_prefix]
|
||
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
|
||
[PREFIX]
|
||
|
||
By default, \`make install' will install all the files in
|
||
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
|
||
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
|
||
for instance \`--prefix=\$HOME'.
|
||
|
||
For better control, use the options below.
|
||
|
||
Fine tuning of the installation directories:
|
||
--bindir=DIR user executables [EPREFIX/bin]

||
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
|
||
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
|
||
--with-pkgversion=PKG Use PKG in the version string in place of "GNU libc"
|

||
specify an integer to scale the timeout
|
||

|
||
|
||
Some influential environment variables:
|
||
CC C compiler command
|
||
CFLAGS C compiler flags
|
||
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
|
||
nonstandard directory <lib dir>
|
||
LIBS libraries to pass to the linker, e.g. -l<library>
|
||
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
|
||
you have headers in a nonstandard directory <include dir>
|
||
CPP C preprocessor
|
||
CXX C++ compiler command
|
||
CXXFLAGS C++ compiler flags
|
||
|
||
Use these variables to override the choices made by `configure' or to help
|
||
it to find libraries and programs with nonstandard names/locations.
