Bug#742852: belle-sip: FTBFS: unexpected token `am__api_version='1.14''

[Aaron M. Ucko]

Source: belle-sip
Version: 1.2.4-1
Severity: serious
Justification: fails to build from source

Builds of belle-sip against automake 1.14.x (as present in unstable
these days) have been failing:

  ./configure: line 2571: syntax error near unexpected token `am__api_version='1.14''
  ./configure: line 2571: `am__api_version='1.14''

Could you please take a look?

Thanks!
