kconfig: Warn if there is more than one help text
Avoids mistakes like in the following real-world example, where only the
final help string ("Say Y...") was used. This particular example was
fixed in commit 561b29e4ec8d ("media: fix media Kconfig help syntax
issues").
config DVB_NETUP_UNIDVB
...
select DVB_CXD2841ER if MEDIA_SUBDRV_AUTOSELECT
---help---
Support for NetUP PCI express Universal DVB card.
help
Say Y when you want to support NetUP Dual Universal DVB card
...
This now prints the following warning:
drivers/media/pci/netup_unidvb:13: warning: 'DVB_NETUP_UNIDVB' defined with more than one help text -- only the last one will be used
Also free() any extra help strings.
