+[PATCH] Fix build on SPARC
+
+On SPARC, the definitions of B2500000, B3000000, B3500000 and B4000000
+are not necessarily available, so use those values only if defined in
+the kernel headers.
+
+It fixes SPARC build failures such as:
+
+src/serial.c: In function '_serial_baudrate_to_bits':
+src/serial.c:73:30: error: 'B2500000' undeclared (first use in this function)
+         case 2500000: return B2500000;
+                              ^
+src/serial.c:73:30: note: each undeclared identifier is reported only once for each function it appears in
+src/serial.c:74:30: error: 'B3000000' undeclared (first use in this function)
+         case 3000000: return B3000000;
+                              ^
