 1544 \`configure' configures lxc 4.0.10 to adapt to many kinds of systems.
 1545 
 1546 Usage: $0 [OPTION]... [VAR=VALUE]...
 1547 
 1548 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1549 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1550 
 1551 Defaults for the options are specified in brackets.
 1552 
 1553 Configuration:
 1554   -h, --help              display this help and exit
 1555       --help=short        display options specific to this package
 1556       --help=recursive    display the short help of all the included packages
 1557   -V, --version           display version information and exit
 1558   -q, --quiet, --silent   do not print \`checking ...' messages
 1559       --cache-file=FILE   cache test results in FILE [disabled]
 1560   -C, --config-cache      alias for \`--cache-file=config.cache'
 1561   -n, --no-create         do not create output files
 1562       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1563 
 1564 Installation directories:
 1565   --prefix=PREFIX         install architecture-independent files in PREFIX
 1566                           [$ac_default_prefix]
 1567   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1568                           [PREFIX]
 1569 
 1570 By default, \`make install' will install all the files in
 1571 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1572 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1573 for instance \`--prefix=\$HOME'.
 1574 
 1575 For better control, use the options below.

 3502 # actually supported "in the wild" to an acceptable degree.
 3503 # See automake bug#10828.

 3505 # by default if the 'rm' program in use doesn't match our expectations; the

 3509 Oops!
 3510 
 3511 Your 'rm' program seems unable to run without file operands specified
 3512 on the command line, even when the '-f' option is present.  This is contrary
 3513 to the behaviour of most rm programs out there, and not conforming with
 3514 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3515 
 3516 Please tell bug-automake@gnu.org about your system, including the value
 3517 of your $PATH and any error possibly output before this message.  This
 3518 can help us improve future automake versions.

 3527 Aborting the configuration process, to ensure you take notice of the issue.
 3528 
 3529 You can download and install GNU coreutils to get an 'rm' implementation
 3530 that behaves properly: <https://www.gnu.org/software/coreutils/>.

 3532 If you want to complete the configuration process using your problematic
 3533 'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
