Add a way to skip checking if extensions work (#915)

@@ -410,6 +410,7 @@ Here's the list of all the supported environment variables:
 | | `IPE_DEBUG=1` | By setting this environment variable, the script will print all the commands it executes (it will be very verbose, useful only for debug purposes) |
 | | `IPE_PROCESSOR_COUNT` | By default all available processors. Set this environment variable to override the number of processors detected by the script (used for parallel compilation) |
 | | `IPE_DONT_ENABLE=1` | By default the script will install and enable the extensions.<br />If you want to only install them (without enabling them) you can set this environment variable.<br />To enable the extensions at a later time you can execute the command `docker-php-ext-enable-<extension>` (for example: `docker-php-ext-enable-xdebug`).<br />**Beware**: installing some PHP extensions requires that other PHP extensions are already enabled, so use this feature wisely. |
+| | `IPE_SKIP_CHECK=1` | By default the script will check if the extensions can be enabled: if you want to skip this check, you can use this flag.<br />**Beware**: extensions may be enabled even if they break PHP: use this function wisely. |
 | | `IPE_KEEP_SYSPKG_CACHE=1` | By default the script will clear the apt/apk/pear cache in order to save disk space. You can disable it by setting this environment variable |
 | lzf | `IPE_LZF_BETTERCOMPRESSION=1` | By default `install-php-extensions` compiles the `lzf` extension to prefer speed over size; you can use this environment variable to compile it preferring size over speed |
 | event | `IPE_EVENT_NAMESPACE=`... | By default, the `event` classes are defined in the root namespace. You can use this environment variable to specify a custom namespace |
