Fabrice Fontaine 3a9261ddd9 package/libusb-compat: set LIBUSB_1_0_SONAME 
LIBUSB_1_0_SONAME is detected since version 0.1.6 and
b6f5a2fe12

The detection mechanism is based on sed, here are the more relevant
parts:

 shrext_regexp=`echo "$shrext_cmds" | sed 's/\./\\\\./'`
[...]
 [AS_VAR_SET([ac_Lib_SONAME], [`ldd conftest$ac_exeext | grep 'lib[$2]'$shrext_regexp | sed 's/^@<:@ \t@:>@*lib[$2]'$shrext_regexp'/lib[$2]'$shrext_regexp'/;s/@<:@ \t@:>@.*$//'`])])

However, this mechanism is broken with sed 4.7 and will return the
following 'silent' error:

checking for SONAME of libusb-1.0... sed: -e expression #1, char 40: Invalid back reference
unknown

Moreover, it also raises the following build failure on one of the
autobuilder because an empty line is added to LIBUSB_1_0_SONAME:

checking for SONAME of libusb-1.0... checking
libusb-1.0.so.0

Makefile:284: *** missing separator.  Stop.

We could patch patch m4/au_check_lib_soname.m4 to fix the mechanism
however this is difficult without reproducing the autobuilder failure
and upstream seems dead so just set LIBUSB_1_0_SONAME

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.

If you would like to contribute patches, please read
