 > \t@:>@*lib[$2]'$shrext_regexp'/lib[$2]'$shrext_regexp'/;s/@<:@
 > \t@:>@.*$//'`])])

 > However, this mechanism is broken with sed 4.7 and will return the

 > 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
